Thanks for pointing out that unset is a shell command. I come from a mainframe background (please don't laugh) and will readilly admit to getting thoroughly confused between the various shells etc. I had tried the 
delete $ENV{LIBPATH}

and it's right near the top of script.

The weird thing is, that whilst it does replicate the unset command on going into the called routine, unlike the unset command it still causes a 'Total Environment allocation failure'.

I realize this is now getting off of perl per se and more into shell commands - but I beg your indulgence, does 'unset LIBPATH' do anything other than delete the path?

I did a comparison of env before and after issuing the command, and aside of the LIBPATH no longer being present, the only other difference was addition of the phrase "SHLVL=1".

Appreciate your time in responding.
