Ok  but same effect.

[neteler at localhost grass70]$ /usr/bin/geos-config --libs
-L/usr/lib64 -lgeos

[neteler at localhost grass70]$ ldd /usr/lib64/libgeos.so
        linux-vdso.so.1 =>  (0x00007fff2e1fe000)

[neteler at localhost grass70]$ file /usr/lib64/libgeos.so
/usr/lib64/libgeos.so: symbolic link to `libgeos-3.0.3.so'

[neteler at localhost grass70]$ file /usr/lib64/libgeos-3.0.3.so
/usr/lib64/libgeos-3.0.3.so: ELF 64-bit LSB shared object, x86-64,
version 1 (SYSV), dynamically linked, stripped

The RPM looks ok but I'll recompile it from the source tarball.
