After upgrading to 12.04, I wasn't able to run GIMP. Now I installed the latest 2.8 from PPA, and still am unable to run it. I get the error:
gimp: error while loading shared libraries: libgegl-0.0.so.0: wrong ELF class: ELFCLASS64
strangely enough, gimp is 64-bit:
$ file /usr/bin/gimp-2.8 /usr/bin/gimp-2.8: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs)....
So why can't I run it? I reinstalled libgegl, I have 0.0.22 and 0.2.0 versions installed.
