I think I figured it out. expand_path uses the perl function getlogin()
to expand the username. getlogin is not guaranteed to return true, and
this depends on the system. So on some systems (mine, for example), we
need to use getpwuid instead. It's an easy patch, I'll do it tonight.

Today I noticed that on my Linux work computers running Perl 5.8.5 and
5.8.6, the following produced a listing of the subdirectories of my
home directory:
$ perl -e 'use PDL::AutoLoader; print join " ",
PDL::AutoLoader::expand_path("+~");'
But on my Linux home computer running Perl 5.8.8, it produced no
output. Manually substituting /home/derek for the ~ produced the
desired output. Why would tilde expansion work on one system and not
another? All machines are running PDL 2.4.3. I looked through the
"man perldelta"s and found no incompatibility changes. '$ cd ~' works
from within my bash shell, so I don't think that's an issue. I don't
think it's a PDL issue, but rather think that it has to do with my
local configuration (which isn't tweaked in any way from the stock
Mandriva configuration). Any ideas?
thanks,
Derek
