problems installing libwww-perl on cygwin

[Steve Kelem]

It was suggested that I direct this message to the Cygwin group.

I have downloaded the latest Cygwin and the latest perl compiled for 
cygwin.  I'm trying to build the libwww-perl-5.48 module and running 
into a strange problem during "make test".  Perl just hangs while 
executing a perfectly normal statement, both inside and outside the perl 
debugger.

Thanks for your help,
Steve Kelem

I'm having the same problem with libwww-perl-5.48.  I have perl 5.6.0,
compiled for cygwin under Win NT 4.0 SP6a.  It builds ok, but fails in
the test rules-dbm by just hanging.

Here's the debug output:
{KELEM:kelem:228} perl -d -I../.. -I../../lib rules-dbm.t
Default die handler restored.

Enter h or `h h' for help, or `man perldebug' for more help.

*** At this point, it hangs.  I have to use Win NT's Task Manager to
kill the perl task.
