The -I/usr/local/include is added for some other library that Guile
depends on -- GMP or libgc or something else.

For example on my system I have Guile installed into /opt/guile, and
libgc and everything else in /usr, and I get:

  $ guile-config compile
  -pthread -I/opt/guile/include/guile/2.0

Depends on your system, I think.  But yes, this is a danger.  Hopefully
it won't be as "dangerous" when we live in a 2.0+-only world.  I have
been meaning to write an article or FAQ about /usr/local, and this is a
good point.

Cheers,
