When Fink scans packages, VirtPackage.pm doesn't recognize Growl version strings of the form 1.2.2f1, as used by the Growl Fork.
The error is:
Use of uninitialized value $growl_version in string eq at /sw/lib/perl5/Fink/VirtPackage.pm line 1721.
If I run fink-virtual-pkgs --debug, it says:
: - system-xfree86 provides xfree86-base-threaded - checking for Growl... found, Growl - checking for Growl version... Use of uninitialized value $growl_version in string eq at /sw/lib/perl5/Fink/VirtPackage.pm line 1721. unknown Package: 64bit-cpu :
