[Bioperl-l] Issue with Bio::SearchIO::psl (was: Bioperl bug 1977)

[Chris Fields]

I just committed a fix to Bio::SearchIO::psl.  It may take about 20  
minutes from now to update on CVS. This seems to work with or w/o the  
-w shebang flag on Mac OS X.

Let me know if you have more problems with it.
