I'm not at work, so I can't look up the build source, but this reminds me of
a problem I had when I first tried building Ruby with Tcl/Tk8.3.

When the make has made Ruby and goes to work on making the extensions, there
are some *.rb scripts that it runs in order to check for various versions of
Tcl and Tk on various paths, which at that time didn't include a check for
then-new Tcl and Tk 8.3 versions. So not finding them, the extension for
Tcl/Tk was never built. (My situation was also complicated somewhat further
because I was building both Ruby and Tcl/Tk with
./configure --prefix=/non-standard-dir.) To track this down the first time,
I just did the simple brute force thing of running make with some trace
flag, and stuck print statements in the various *.rb scripts that were being
run until I had another one of those "revelations of the obvious".
