I'd like to turn RANCID (www.shrubbery.net/rancid) into a package.  But, It's
configure script attempts to determine the location of various tools (mkdir,
diff, perl, expect, etc) to both have proper interpretter lines (#! ...)
and build an appropriate PATH for it's cron script.

Problem is that the first this it finds is the tools that pkgsrc linked/wrapped
in net/rancid/work/.tools/bin.  Just like the problem mentioned in
http://mail-index.netbsd.org/tech-pkg/2004/12/31/0018.html, but that solution
does not seem universal.

Any suggestions on how to ignore, resolve, etc the real tools?
