GNUmail won't install

[Dushan Mitrovich]

I've been trying to install GNUmail on my system (X.6.5) but keep 
running into 'configure failure' problems.  Macports is up to date.

On trying to install the dependencies individually (SQLClient, 
Performance, gnustep-base, oniguruma5, and Pantomime), I'm always 
informed that gnustep-base failed to install.  Here are the last parts 
of the main.log files (lines beginning with four blank spaces are 
continuation lines) when trying to install
______

:info:configure I don't seem to be able to use your Objective-C compiler

compiler installation.

libgcc_s and
     libobjc

requires you to play

for more help.

Pantomime:
:msg:main --->  Dependencies to be installed: gnustep-base

:error:configure The following dependencies were not installed: gnustep-base

SQLClient:

:debug:clean Starting logging for gnustep-base
:error:configure The following dependencies were not installed: Performance
     gnustep-base
:error:configure Status 1 encountered during processing.

The log file for gnustep-base seems to suggest that there is no 
functioning Objective C compiler.  How do I address this?  EasyFind is 
able to find hundreds of 'objc' files and folders, but I guess that 
doesn't prove anything.

Help figuring out what I need to do, and check, would be much appreciated.
