This bug is possibly related to BUG#44425.
When using LaTeX::Driver with mod_perl, the environment variable
TEXINPUTS is not passed on from the perl %ENV to the pdflatex system
call. This looks to be a known limitation with mod_perl 2.0
(there is a thread on perlmonks:
http://www.perlmonks.org/?node_id=767907 ).
I managed to get around the issue by patching LaTeX::Driver. While it
certainly managed to fix things for my situation I'm sure you can
appreciate that passing TEXINPUTS explicitly and as an environment
variable are not equivalent, so I would be happy if anyone proposed a
better solution. I have left the system call used for MS Win unchanged
as I do not know how mod_perl is handled on that system.
