any idea?

You can use macports to install basemap and/or the geos library.

[dev66]

yes, you are right. however, certain circumastances require that i compile the package myself.

besides, using macports does not help improving the basemap package, which IMO eventually should be able to compile on lion w/o such issues...

thanks

the problem is with the geos lib dependency, not basemap. You could take a look at the macports package to see how they work around those compiler errors. Perhaps using clang instead of gcc (or vice versa)?
