Problems with XML_Client.pm

[Chip Yamasaki - BuyDomains.com]

I've been pulling my hair out over XML_Client.pm and could sure use some
help.

Basically, I'm driving it from my own Perl script on a Linux box and I'm
having some degree of success, but hitting a wall.  I've littered
XML_Client.pm and OPS.pm with debugging statements and have determined that,
while it IS authenticating just fine, the registration command that I'm
sending is resulting in the OPS->read_data method reading 0 bytes.

Anybody have any experience with this problem and maybe a solution?
