sys-libs/db won't emerge

[B-one]

When updating world, i get the following error :

Code: Select all

* Messages for package sys-libs/db-4.5.20_p2-r1:

 * Unable to determine VM for building from dependencies:
 *
 * ERROR: sys-libs/db-4.5.20_p2-r1 failed.

I have been trying emerge --depclean, revdep-rebuild but the error is still here

Thanks for your help ^^

what does

Code: Select all

eselect java-vm list

say? If it lists some choices, choose the newest one and do

Code: Select all

eselect java-vm set VM

where VM might be sun-jdk-1.6 or some such.

When i type eselect java-vm list i get:

Code: Select all

Available Java Virtual Machines:
  [1]   blackdown-jdk-1.4.2
  [2]   sun-jdk-1.6  system-vm

eselect java-vm show :

Code: Select all

Current system-vm
  sun-jdk-1.6
Current user-vm
  (unset)

when i try to type eselect java-vm set 1/2 i get this error:

Code: Select all

!!! Error: Usage [user|system] [vm]
Killed

EDIT: ok, i managed to chang it from sun-jdk to blackdown-jdk but db emerge still fails.

this is the detailed error, maybe it will help:

Code: Select all

Unless you really know what you do, you don't want to use the Blackdown JDK.

Most likely you updated to Python 2.5, but didn't run the python-updater script afterwards as you are held to. Hint: If this is the case and you unmerged Python 2.4 in between, make sure to make use of the relevant options this script provides.

yes it has something to do with python.
i unmerged python but now i can't emerge anymore ...

Code: Select all

/usr/bin/emerge: /usr/bin/python: bad interpreter: No such file or directory

is there another way of reinstalling it ?

[B-one]

up i'm really stuck without being able to emerge

So you unmerged python? Use the little search box in the upper right corner and do: "unmerged python" then press enter and you'll eventually be led [topic=702256]here.[/topic]

You're original problem would have been solved by doing the following:

Code: Select all

#python-updater -i
#emerge -avuDN world
