Dear Drew, dear GAP-Forum,

The problem you mention is (maybe) a bug in versions 3.4.3 and 3.4.4 of
GAP under DOS.

The variable PKGNAME which contains a list of possible paths to the
directory with the shared packages is not set correctly (in fact it is
empty or contains only one (wrong) path, I think). You should add the
correct path for your system, maybe with a command similar to:

Add(PKGNAME, "c:\\gap3r4p4\\pkg");

Note that the backslashes have to be typed twice.
After this RequirePackage should work fine.
