I figured out why this isn't working. There already exists a module called
B.pm in the perl/lib directory. If you change the name of module B.pm to
something else, then it works!!
Thanks!!

Given A.pm
===========
package A;
sub a { return "a!\n"; }
1;
===========
and B.pm
===========
package B;
use A;
sub b { print A::a(); }
1;
===========
and C.pl
===========
use B;
B::b();
===========
running C.pl should print "a!\n".
Unfortunately, this simple example fails to work for me, though I can
make virtually the same call work fine using much more complicated
modules I've written.
The principle is that you specify the package space. For example, if in
your module you
use Symbol;
then you should be able to generate globs at need with
my $glob = Symbol::gensym;
"gensym" being a function in the "Symbol" namespace.
I've done this in lots of modules.
So could somebody point out to me what I'm doing stupid, so no one on
this list will copy the part of the above example that I'm doing
*wrong*? lol!!
