| I know that some people reported similar problems, but perhaps the
| unisntalled.pc case has not been fixed?  If a patch could be provided
| which fixes this, that would be helpful.  For now we are going to
| have to backout to pkg-config 0.23.

As a workaround, adding $ and () to the filtering list in
parse.c:strdup_escape_shell should work around this.  It's not the real
fix, but it should work for now.
