Unfortunately, this "port" (which the author himself says is not really a
port),
is not as good ad the following set of files directly from
the Arcadia Project at

ftp://liege.ics.uci.edu/pub/irus/software_releases

The files you want to get are:

04/21/94  12:00a               605,896 aflex-ayacc_1.4a.tar.Z
04/22/94  12:00a               184,272 aflex-ayacc_1.4a_ps_docs.tar.Z
09/22/95  12:00a                41,827 aflex_gnat_beta.tar.Z
09/28/95  12:00a                41,295 ayacc_gnat_beta.tar.Z
07/07/98  09:43p                 4,154 README.aflex-ayacc


Assuming you are using GNAT, here are some installation instructions:

When you unpack the 605,896 aflex-ayacc_1.4a.tar.Z, you will have
VADS-compatible source code (files have .a extension) in the two src
directories.  You need to gnatchop these files (then delete the original .a
files).

Then you can unpack the two gnat_beta archives, and copy the .ad[bs] files
into the corresponding src directories, overwriting the gnatchopped versions
of these files.

Finally, in the corresponding src directories do

gnatmake aflex

and

gnatmake ayacc

The doc directories in the distribution contain .tex documentation, but the
ps_docs archive I listed above has the documentation in Post Script form.
