Geos 3.3.0 installation problem on Lion

[pico303@…]

When installing Geos 3.3.0 (for PostGIS), I got the following error:

:info:build Undefined symbols for architecture x86_64:

:error:build Target org.macports.build returned: shell command failed (see log for details)

It did work if I installed Geos as follows:

sudo port install geos configure.cc=gcc-4.2 configure.cxx=g++-4.2
