CONFIG_DEVTMPFS: is not set when it should be

Problem

emerge  sys-fs/udev

* Messages for package sys-fs/udev-200:

 *   CONFIG_DEVTMPFS:    is not set when it should be.
 * Please check to make sure these options are set correctly.
 * Failure to do so may cause unexpected problems.

Solution

 You have to check the following  option in your kernel config :

 Device Drivers-> Generic Driver 
* Maintain a devtmpfs filesystem to mount at /dev.  

 For getting the devfs automatically mounted at boot time it makes sense to also enable the option  
* Automount devtmpfs at /dev

CONFIG_DM_CRYPT: is not set (required for cryptsetup)

Problem

* Messages for package sys-fs/cryptsetup-1.4.3:

*   CONFIG_DM_CRYPT:   is not set (required for cryptsetup)

*

* Please check to make sure these options are set correctly.

* Failure to do so may cause unexpected problems.

* This ebuild introduces a new set of scripts and configuration

* than the last version. If you are currently using /etc/conf.d/cryptfs

* then you *MUST* copy your old file to:

* /etc/conf.d/dmcrypt

* Or your encrypted partitions will *NOT* work.

* Please see the example for configuring a LUKS mountpoint

* in /etc/conf.d/dmcrypt

*

* If you are using baselayout-2 then please do:

* rc-update add dmcrypt boot

* This version introduces a command line arguement 'key_timeout'.

* If you want the search for the removable key device to timeout

* after 10 seconds add the following to your bootloader config:

* key_timeout=10

* A timeout of 0 will mean it will wait indefinitely.

*

* Users using cryptsetup-1.0.x (dm-crypt plain) volumes must use

* a compatibility mode when using cryptsetup-1.1.x. This can be

* done by specifying the cipher (-c), key size (-s) and hash (-h).

* For more info, see http://code.google.com/p/cryptsetup/wiki/FrequentlyAskedQuestions#6._Issues_with_Specific_Versions_of_cryptsetup

Solution

- Update kernel

- Check device drivers -> Multiple devices driver support (RAID and LVM) -> Crypt target support 

- emerge sys-fs/cryptsetup

sys-apps/sysvinit-2.88-r4" is blocking sys-apps/util-linux-2.22.2

Problème :

emerge -p system
[blocks B      ] <sys-apps/sysvinit-2.88-r4 ("<sys-apps/sysvinit-2.88-r4" is blocking sys-apps/util-linux-2.22.2)

Solution :

It means that older version of sys-apps/sysvinit is blocking sys-apps/util-linux.
So you have to upgrade sys-apps/sysvinit before sys-apps/util-linux.
Or you can make the following :

emerge -uDv1 sysvinit util-linux

Problem emerging firefox-10.0.11 with libpng

Problem :

I had the following problem when I builded firefox 10.0.11 :

[i]checking for png_get_acTL in -lpng... yes
configure: error: --with-system-png requested but no working libpng found
*** Fix above errors and then restart with               "make -f client.mk build"
make[2]: *** [configure] Error 1
make[2]: Leaving directory `/var/tmp/portage/www-client/firefox-10.0.11/work/mozilla-esr10'

 *
 * If you need support, post the output of `emerge --info '=www-client/firefox-10.0.11'`,
 * the complete build

Solution :

There were a conflict with an old version of libpng.To solve the problem, I had to delete libpng files in  /usr/local/include and /usr/local/lib. Thanks to ssuominen for the solution :  http://forums.gentoo.org/viewtopic-p-7215412.html#7215412
