It is sometimes a useful diagnostic step when we're trying to figure out a problem, but it is not supposed to be an everyday activity for users. What you're doing wrong is that you're *setting* configure.args, *overriding* the dozens of configure.args the portfile already sets that make it function correctly. But there is no syntax for appending to (rather than overriding) configure.args (or any other internal portfile option) at the command line.

Thanks for the hints. I didn't know. Funny enough, the installation 
seemed to work fine, after I "fixed" the missing library issue through 
symlinks.

So I better do not use configure.args on the command line. Is editing 
the Portfile a safe option? Probably not, I would assume :-(

I have a similar issue with libkml, where gdal expects version >= 1.3.0 
(never released, only available from trunk). So I would have to install 
libkml under /opt/local rather than anywhere else which would require 
the configure argument --with-libkml=/path/to/libkml
