GPSDrive package in unstable feed

This is probably a dumb question arising from me trying to do something
I probably shouldn't but....
 
In trying to install using IPKG gpsdrive_2.10pre2-r1 from the unstable
feed onto an IPAQ 3870 with Familiar 0.8.4 and GPE 2.7,
I get the following error: Error: Cannot statisfy following
dependencies linbx11-6 >= 6.2.1cvs 20050331
 
upon checking I already have libx11-6.2.1r4 all installed correctly.
 
 
I suspect that if I get this dependency resovled there may well be
others that will crop up.
 
However, any hints at fixing/working around this problem? Or should I
give up now?
