According to our AIX sysadmin, R-1.9.1 actually compiles a lot more cleanly than R-1.8.1 and prior. I take it the recent reports of difficulties has to do with (possibly outdated) GCC. We have no problem with xlc/xlf.

The trouble we're having is getting R to link against readline in 64-bit. Haven't figure out how to do that yet. Life w/o readline is rather trying...
