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

The problem isn't that the Bio::SeqIO::genbank module can't be found  
but what is indicated by the nested error message (i.e., the error  
that caused loading the module to fail): "Weak references are not  
implemented in the version of perl".

Bio::Species imports the weaken() and isweak() functions from  
Scalar::Util (and Bio::SeqIO::genbank requires Bio::Species).  
Apparently the perl installed in that system has been compiled such  
that it won't support weak references.
