AW: fam0.8.4opie: cannot install packages to cf (iPAQ 3660+Jacket)

I found something - maybe a bug - in the /usr/bin/ipkg-link script.
On my iPAQ, I need every library linked in the following way:
(where n.m.o is the version number and /media/cf my target media for the
package installation)

/usr/lib/LIBRARY.so.n.m.o -> /media/cf/usr/lib/LIBRARY.so.n.m.o
/usr/lib/LIBRARY.so.n.m -> /media/cf/usr/lib/LIBRARY.so.n.m.o
/usr/lib/LIBRARY.so.n -> /media/cf/usr/lib/LIBRARY.so.n.m.o

Note, that the target version number is always the same and complete.

The ipkg-link script creates links for the files installed on /media/cf,
taken from the control-file of the packages. In these control-files the
libraries are listed with full version number and with shortened ones.
As ipkg-link simply parses this list, the links consequently look like:

/usr/lib/LIBRARY.so.n.m.o -> /media/cf/usr/lib/LIBRARY.so.n.m.o
/usr/lib/LIBRARY.so.n.m -> /media/cf/usr/lib/LIBRARY.so.n.m
/usr/lib/LIBRARY.so.n -> /media/cf/usr/lib/LIBRARY.so.n

So only the first link really links a library, whereas the following do not
exist.
The best possible solution would be to change the ipkg-link script in order
to create links for the shortened version numbers as well, all pointing to
the same library on the target media (as shown above).
One could e.g. compare the last character with numbers and than crop the
filename, create a link and repeat the procedure until one reaches the
".so"...

I think this has to reach the maintainers of ipkg-link, since it concerns
nearly every package installation with a target othear than the root-fs. I
can hardly install a single package without errors...

best regards, heiko.
