After some tries of uninstalling pygments now the version 1.3.1 is successfully
uninstalled. I have used cave uninstall --all-versions pygments
--perform-program 'gdb --args cave perform' -x
After compiling paludis using the CXXFLAGS -ggdb3 the pygments version 0.9 left
in the system. Look at this:
amd64x2 / # cave uninstall --all-versions pygments --perform-program 'gdb --args
cave perform' -x
Done: 1056 steps
These are the actions I will take, in order:
