rvosa has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks,

how might I find out what the library path variable is called on any given OS? I.e. how can I figure out the name of the env variable, $DYLD_LIBRARY_PATH or $LD_LIBRARY_PATH or %PATH%, that points at shared libraries (e.g. /usr/local/lib)?

Thanks!
