Thanks Eric.  This was enough of a hint for me to fix it.

-Dave

For everyone's records (if interested), to get things to work on this LINUX 
machine (Enterprise-Version3 Intel EM64T):

(1) Remove "-malign-double" flag for COMPSWIT within the FDEFAULT.SH file.
(2) Change LIBDIRS_LINUX in /opt/aips/31DEC04/Y/SERVERS/XAS/Makefile from
LIBDIRS_LINUX    = -L/usr/X11R6/lib to
LIBDIRS_LINUX    = -L/usr/X11R6/lib64

Then run install.pl.

Dear Eric,

Using the default installation from install.pl, I was unable to get XAS to 
compile.

It returned the message below.  I'm running gcc version 3.2.3 under Red Hat 
Enterprise Linux WS version 3 (out of the box 470-n from Dell).

Upstream, install.pl returned this comment which may be relevant:

---
AipsWiz: Running Readline 'configure' in quiet mode, and then make...
loading cache ./config.cache

recognized creating ./config.status
--- 

My machine is a dual processor, and I believe that I'm running Intel EM64T with 
32-bit applications (hyper-threading).

To get the rest of the AIPS compiled, I turned off the "-malign-double" flag for 
COMPSWIT within the FDEFAULT.SH file.  I'm not sure if there are any negative 
impacts to this.  Anyway, AIPS seems to work ok, except that I do not have XAS. 

Do you have any suggestions for getting XAS to work on my machine?  We tried to 
set the LD_LIBRARY_PATH to point to X11, but that did not seem to help.

Thanks for any help you may provide,

-Dave Frayer
