I gave it a try again, just to see what happens.

The script first looks for an awk and finds /usr/bin/nawk, and then 
explicitly later looks for gawk.  export GAWK=/usr/bin/nawk got me over 
that test.

It requires both an ecj.jar and a libgcj.jar.  Are both necessary?

A "-bash-3.2$ ./configure 
--with-ecj-jar=/export/home/ravn/download/ecj.jar --with-ecj 
--with-libgcj-jar=/export/home/ravn/download/ecj.jar 
--with-xalan2-jar=/export/home/ravn/download/ecj.jar 
--with-xalan2-serializer-jar=/export/home/ravn/download/ecj.jar 
--with-xerces2-jar=/export/home/ravn/download/ecj.jar" got me to
configure: error: "motif headers were not found -
        try installing lesstif-devel."

which I now remember to be the place where I gave up the last time as 
apparently Motif is not available under OpenSolaris and "pkg search 
lesstif" did not show any packages.

I'll look at building lesstif and see what happens then...
