in reply to Very basic question!
Yes, it is possible that you do not have a "path to perl" if perl is not installed on your system.
You might wish to search for files or directories which have the word 'perl' in it. On a UNIX system which has the Korn shell installed, type 'cd /' followed by a return, 'ksh' followed by a return and then type 'find . -name *perl*' followed by a return.
The directory which has the perl interpreter called 'perl' is probably your path. Add it to your existing path and also, in the Korn shell, type 'export PERL5LIB = "mypath";' where mypath is the directory you found.
