[pm-h] How to update @INC from within a script?

[Jay Vogt]

All,

Thanks for the suggestions. Error came from a mistaken belief
that the BEGIN statement would be executed first regardless of
its position in the script. All worked fine once I move the BEGIN
block to the very beginning of the script as Kristofer indicated.
Not sure where I go the notion that BEGIN statement did not have
to be at the start of the script.

Wade - the reason for the perl with non-existent directories for @INC
is because it is sent to clients who can install in any directory they
want. I don't suppose that @INC can point to directories with
relative paths or variables in them.

Thanks,

Jay Vogt
