[Bioperl-l] Fw: broken Bio::SeqIO in bioperl on OS X (fink)

Fri Feb 27 18:19:36 UTC 2009

As for now, it looks like the errors resulted from the user using both fink and CPAN to install modules, in combination with the recent OS X Security Update, whcih reverted one of the system perl modules.

thanks,

- Koen.
