It is very likely that your GEOS installation is too old. Are you trying to install rgeos 0.1-8, available since yesterday from CRAN? This should check that GEOS is >= 3.2.2, so perhaps you are trying to install an earlier version of rgeos? You have not provided your full configure report, so it is hard to tell.
In addition to libgeos, you need libgeos-dev and libgeos-c1. If you cannot meet the requirement on GEOS from a Debian binary package, consider installing from source - the Debian binary builds are rather out-of-date. Be sure to update sp before installing rgeos. Finally, this question is better suited to R-sig-geo than R-help.
