Summarising here:

rgeos is tested regularly and frequently, so the issue here is on your 
platform, I'm afraid. How did you install rgeos (from source)? Are other 
versions of GEOS present not installed as RPMs? The simplest way to 
resolve this is to install GEOS from source, because you avoid relying on 
upstream packaging. This will however interfere with other software that 
may depend on your existing GEOS.

We know that rgeos runs its examples across multiple platforms, but we 
don't know where your GEOS came from. You can see that rgeos works on 
Linux platforms from:

Please do not post HTML. Really.
