Compiling R under IBM-AIX using IBM native C-compiler

Would anybody have any experience with that ?
(that's the first time I use AIX)
The configure step is incredibly slow... any hint ?

It seems to depend on exactly what AIX you have.  With 4.3 on RS/6000
hardware I can compile with either gcc or the native tools (though not
with a mixture of the two). The configure and build is very slow, and is
even worse with gcc.   I don't actually *use* R on AIX, but it does pass
make check.  There are also some R users on AIX at CMU, I believe.

OTOH, someone has reported problems with a more modern AIX on PowerPC
hardware.
