[Bioperl-l] Re: Problem with Bio::DB::DBI::Pg after upgrading to core-1.5.1 and latest cvs

[Hilmar Lapp]

Bioperl-db required some changes to work fine with the 1.5.x releases, 
so it is critical that you upgrade bioperl-db as well if you upgrade 
Bioperl to 1.5. I believe the reason you're getting the error is a 
version incompatibility. SimpleDBContext does implement dsn(), and 
Pg.pm doesn't use SimpleDBContext as a literal anywhere.

However, you're saying that you are using the latest cvs update of 
bioperl-db, so maybe you haven't installed your upgraded bioperl-db 
version but did install the previous one?

You can check for individual versions of files by grep'ing for the $Id 
tag. Here's what you should see:

reigen: 9:49 19>perldoc -m Bio::DB::SimpleDBContext.pm | grep '$Id'
# $Id: SimpleDBContext.pm,v 1.5 2005/08/26 19:34:14 lapp Exp $
reigen: 9:51 20>perldoc -m Bio::DB::DBI::Pg.pm | grep '$Id'
# $Id: Pg.pm,v 1.2 2005/08/26 19:34:14 lapp Exp $
reigen: 9:52 21>

Did you run the tests? Was there a problem? If the tests run fine (they 
should) then it is almost certainly older modules installed somewhere 
else in your @INC that interfere with the new ones.
