No. Builds with compilers newer than 4.2 as well. Read the section on "Compiling" in the HOW-TO-INSTALL-OPEN64 document in the main directory. The symptoms you describe are similar to what you would see if you didn't have the *-multilib (or *.686) packages installed on your system. There are some other tips and prerequisites you'll also want to get following instructions above.
Once you do that, with 4.6 you could run into an issue found in "g++: error: unrecognized option 'CG:all_sched=0'" string also in this forum, and read responses on that string.
you answer solved all my problems. thx.
