Thanks for your reports.
I prepared a patch that fixes both these bugs (they're both caused by a wrong
usage of find_library(), as you already found out), but unfortunately I'm not
able to commit it (and consequently to do an upload), even though I'm part of
the DebianGIS team:
$ LANG=C svn commit
svn: Commit failed (details follow):
svn: Authorization failed
[..]
I suspect this happens because the (Unix) group doesn't have write permission.
Therefore, I'm attaching the patch to this mail, hoping that frankie reads this
and acts accordingly (he's away for a couple of days).
Have a nice Sunday,
David
