R-beta: POSIX and regcomp on SGI-IRIX 5.3

Hey Guys,

  I'm trying to install R on an SGI IRIX 5.3 machine. I'm having trouble
getting R to use POSIX regular expressions. Here is the error message I get
when I run help:

> help()
Error in gsub(pattern, replacement, x, ignore.case, extended) : POSIX regular
expressions not available

I looked through the R-help archives and I found a few tips concerning the
problem. I tried them (ie: I installed readline-2.2, regex-0.12, rx-1.5, and
edited ./Makeconf and ./src/include/Platform.h to use the regex libraries.) and
R compiled and installed with no errors. (However, configure still didn't find
regcomp and I edited Makeconf and Platform.h after running configure.) Now,
when I type help() R crashes and dumps the core:

> help()
Segmentation fault (core dumped)

R also crashes when I try to run the image demo:

> demo(image)

        ---- ~~~~~

Type  <Return>   to start :

> opar <- par(ask = interactive() && .Device == "X11")

> data(volcano)
Bus error (core dumped)

Has anyone been able to get POSIX commands on R-0.62.1 to work on an SGI IRIX
5.3 machine?
