Thanks for all your work!

I patched Build.PL like:

-my $ver2func = do(catfile(qw/inc ver2func/));
+my $ver2func = do('./' . catfile(qw/inc ver2func/));

This doesn't work for me, I run into

	perl Build
Can't find appropriate bindings version, check 'xs' directory, it should contains bindings with version <= current GSL version (2.5) at inc/GSLBuilder.pm line 93.

(from inc/GSLBuilder.pm).

But the good news is that I found another way to force a swig
rebuild:

--- a/inc/GSLBuilder.pm

Thanks!

Ack.

I've pushed your and my patches, but I'd rather have another
doublecheck before uploading.
