Reduce Developer

[Mark Brethen]

The developer of reduce has checked in a new set of configure files. When configure is invoked with CC or CXX set (to values other than gcc and g++) then it skips the Mac code that uses gcc explicitly and tries to identity which SDK is available. 

He also has some insight into how it might be used:

The reduce portfile now uses subport=reduce-with-csl and subport=reduce-with-psl (reduce becomes a stub-port that does nothing). The html reference material is compiled and linked with csl. A variant to compile the pdf version is available to both csl and psl users.

Issuing 'sudo port destroot reduce subport=reduce-with-csl' resulted in a build error:

As this is now beyond my capability to diagnose and fix, he has agreed to try running the portfile and see its behavior directly and find out what is going on. He has a Mac with 10.7 on it, and I'm helping to get macports installed.

Would there be someone he could contact with questions? As a middle-man, I probably will not be much help when it comes to tailoring the code to work with macports.
