[GRASS5] Patch to make shared libraries work correctly for RPM packages

[Jan-Oliver Wagner]

Hi,

on behalf of my collegues Silke and Sascha I am sending you
this patch which is required for having shared libraries work
for having adequate RPM packages (we needed this and tested it
for Fedora Core 4).

I am not aware of a email-thread where this has been discussed,
so I just post it here. Silke is currently on the road (again)
and asked me to send this patch as it should not further delayed.

Let me know
whether you like
whether I should commit
whether anyone else wants to commit

Best

	Jan
