This isn't a correct solution, because it would be defined only for
"configure" (but not for "make"). You should set it in your .profile
or other shell rc file. You also need to set C_INCLUDE_PATH and/or
CPATH.

If you want to set an environment variable only for the build process,
you should use the form:

  ./configure VAR1=value1 VAR2=value2 ...

i.e. as configure arguments.

But note that configure will generally use /opt/local globally, not
only for QT. This may be a problem if different versions of some
library are installed in different directories provided in such
paths: you don't know which one will be taken.
