It's just an environment variable like any other; it's not special in
any way.

gnome-terminal is just a terminal emulator; it does not alter the
shell environment.  Whatever /etc/profile.d/atrpms.sh might be (it's
not present on my system), whether or not it sets PERL5LIB (it
shouldn't be set by default) is irrelevant, you can still overrride it
in your shell configuration.

I use PERL5LIB all the time (I maintain the Debian build infrastructure
in Perl and use this for testing uninstalled Perl library code in my
build tree).  But, like LD_LIBRARY_PATH for shared libraries, you use
it to specifially add to the Perl module search path.  Setting it in
your shell will just work as for any other environment variable.
