Could you possibly try adding the env vars to /home/koha/.bashrc or 
/etc/bash.bashrc.local so that it includes:

export PERL5LIB=/usr/share/koha/lib

then reboot (log out/log in is perhaps sufficient.)  I have found that this 
can, in some circumstances, cure the "Can't locate C4" messages.

If this does not help, at least it narrows down other possibilities.
