postgreSQL 6.3.2 and AIX

Does anyone have exeperiences with AIX4.2/postgreSQL 6.3.2?
Now I'm unable to compile it I've got the following error message:
bash-2.01$ gmake
Making postgres.imp
./backend/port/aix/mkldexport.sh postgres /usr/local/pgsql/bin >
postgres.imp
nm: postgres: 0654-200 Cannot open the specified file.
nm: A file or directory in the path name does not exist.
xlc -bE:./backend/postgres.imp -o postgres  ../utils/version.o -lPW -lld
-lnsl -ldl -lm -lcurses
xlc: 1501-228 input file ../utils/version.o not found
gmake: *** [postgres.imp] Error 252

What's wrong?

                                        when it all seems so stupid?
