[Bioperl-l] Bio::Pedigree modules

[Man-Suen Chan]

Hi
I am trying to use the bio-pedigree modules but am having problems getting  them to work. I tried to run a script provided with the module and got the following message:

 /tmp/bioperl-pedigree/scripts/pedplot.pl -p example1.pped -d example1.pdat 
Bio/Pedigree/PedIO/linkage.pm: linkage cannot be found
Exception Global symbol "$name" requires explicit package name at /usr/lib/perl5/site_perl/5.6.0/Bio/Pedigree/Pedigree.pm line 151.

Compilation failed in require at /usr/lib/perl5/site_perl/5.6.0/Bio/Pedigree/PedIO.pm line 437.

For more information about the PedIO system please see the PedIO docs.
This includes ways of checking for formats at compile time, not run time
Can't call method "read_pedigree" on an undefined value at /tmp/bioperl-pedigree/scripts/pedplot.pl line 35.

When I did "make test" I had a lot of tests failed. I think the line that causes the problem is 
require Bio::Pedigree::Pedigree;

I would also be interested in general on anyone's experience with these modules.

Thanks
