>Description:

it seems that our libtool's pattern for matching shared libs doesn't like
'.' in the library name.  

The way libtool checks to see if a shared library is available from the
-lfoo flag is it looks for libfoo.so (or libfoo_pic.a).  However if you have something like
-lfoo-1.0, it tries to look for libfoo-1.0.so, but the extra '.' throws
off the regexp in the pattern matching.


[using the current pkgsrc libtool's matching]
# echo "/usr/pkgsrc/x11/gtk2/work/.buildlink/lib/libgmodule-2.0.so" | \
   sed 10q | egrep "/lib[^/\.]+(\.so|_pic\.a)$"

no match!

# echo "/usr/pkgsrc/x11/gtk2/work/.buildlink/lib/libgmodule.so" | \
   sed 10q | egrep "/lib[^/\.]+(\.so|_pic\.a)$"
/usr/pkgsrc/x11/gtk2/work/.buildlink/lib/libgmodule.so

found a match!

[using a more relaxed matching that doesn't exclude the '.']
#  echo "/usr/pkgsrc/x11/gtk2/work/.buildlink/lib/libgmodule-2.0.so" | \
   sed 10q | egrep "/lib[^/]+(\.so|_pic\.a)$"
/usr/pkgsrc/x11/gtk2/work/.buildlink/lib/libgmodule-2.0.so

found a match!

	
>How-To-Repeat:

try and create a shared library that links to a -lsomethingwith.inthename
with libtool.  It will complain that no shared lib for -lsomethingwith.inthename
is found.
	
>Fix:

change the matching pattern as shown above.

I didn't make the change myself because libtool touches too many pkgs and 
I wanted extra opinions on this fix.
