Segfaulting perl

When trying to run fetchyahoo (from ports), perl dumps core. It  
appears to be dumping core in OpenSSL. I've tried recompiling/ 
reinstalling all ports related to fetchyahoo, perl, and openssl. This  
happens whether or not I enable SSL in fetchyahoo's configuration.

It gets as far as:

~% fetchyahoo
Logging in insecurely via plaintext as username on Tue Oct 10

zsh: segmentation fault (core dumped)  fetchyahoo

Perl and OpenSSL have been compiled with:

~% egrep -i '^(COPT|CFLAG)' /etc/make.conf
CFLAGS+=-O -pipe -mtune=i686 -g
COPTFLAGS=-O -pipe -mtune=i686 -g

Here's the output of GDB and a backtrace

Core was generated by `perl5.8.8'.
