This is on a brand new 10.9.2 machine with the latest Xcode and command line
developer tools and a freshly installed, updated fink. It does the same thing
when max fink build jobs is set to 1.

ERROR: Unbound variable: define
[Compilation hangs here]
I spent some time trying to chase this down, with partial success. What
I found:
This is a caused by another new "feature" of Apple's new clang. This
time, it is an "improvement" of the preprocessor that crashes the rather
horrible macro games the guile18 build system is playing.
In short, a preprocessor macro with an empty expansion now eats a
preceding newline, but guile18 (in its guile-snarf script) depends on
certain macro expansions starting a new line. This works with the
previous clang or also with "gcc-fsf4.8 -E" as a preprocessor, but not
with "gcc -E" from the new clang. The result is that libguile is
miscompiled and does not contain the symbol "define" (as well as a
couple dozen others).
It is not hard to patch for this problem, see the attached patch file.
The "Unbound variable: define" error then disappears.
Unfortunately, the build crashes still at the same place, which is the
first time in the build phase that the newly built guile executable is
used. This indicates that it or rather the libguile.dylib is still
miscompiled. This time, the error message is
ERROR: invalid arglist syntax: (hash paren_open SCM alist comma SCM key
paren_close)
Since this comes from the belly of a guile script
(snarf-check-and-output-texi, SCHEME!) and may involve some texinfo
thrown in, I am not sufficiently polyglot and have to give up at this point.
BTW, fink build guile20 crashes at the same place, with a segmentation
fault of the guile executable. I have a crash log if someone wants to
pursue this further.
