Well, just as an idea, there is a portable C library for this at 
http://laurikari.net/tre/ released under LGPL.  If one is willing to 
give up PCRE extensions for speed, it might be worth the work to 
wrap this library using SWIG.

The cheap way in terms of programmer time is to pipe out to grep or 
awk on this one.
