$ apt-file search /usr/lib/libgeos.so
libgeos-dev: usr/lib/libgeos.so
libgeos2: usr/lib/libgeos.so.2
libgeos2: usr/lib/libgeos.so.2.1.1

$ dpkg -s libgeos-dev 
Package `libgeos-dev' is not installed and no info is available.

$ gdal-config --dep-libs
-L/usr/lib -lgeos -lodbc -L/usr/lib -lxerces-c -lpthread -ljasper -lmfhdf -ldf -lgif -ljpeg -ltiff -lpng -lnetcdf -lcfitsio -L/usr/lib -lpq -lz -lpthread -lm -lrt -ldl

$ dpkg -s libgdal1-1.3.1 | grep Version
Version: 1.3.1-0.dgis.stable.2
   (this hasn't changed since March)

I am wondering what changed in the GRASS source so now we need geos devel
packages as well?

New GRASS 6.3+ packages will have to add libgeos-dev to the build-depends
list in the debian/control file.

?
