Compiling alh, MEDM on Snow Leopard (10.6.2)

["Bertrand H.J. Biritz" <bbiritz@ucla.edu>]

Dear Tech-Talk,

It's the holiday season which means new computer (for my dad this  
time) and also compiling code :)

So I tried installing EPICS et al. on a MacBook Pro (2.53 GHz) running  
10.6.2 with MacPorts 1.8.1.
EPICS 3.14.11 went fine, although I needed to deactivate readline  
(6.0.000_2+darwin) as it caused an error – hopefully a problem on  
their end as the package is still in dev, but just in case here is the  
error message

<snip>
../../../../bin/darwin-x86/antelope -l -d ../parse.y
dyld: Symbol not found: _rl_insert
  Referenced from: /Users/Superior/Documents/EPICS/base-3-14-11/lib/ 
darwin-x86/libCom.3.14.11.dylib
  Expected in: flat namespace
<snip>

When I try to compile the latest version of the alarm handler or MEDM  
I get the following error message:

<snip>
ld: warning: in /opt/local/lib/libXmu.dylib, file is not of required  
architecture
ld: warning: in /opt/local/lib/libXm.dylib, file is not of required

architecture
Undefined symbols:
  "_XtAppAddActions", referenced from:
      _awRowWidgets in awAlh.o
<snip>

I double checked the CONFIG_SITE.darwin-x86.darwin-x86 file to make  
sure it is looking in the correct locations:

#
# XDarwin
#
X11_LIB=/usr/X11R6/lib
X11_INC=/usr/X11R6/include/X11
XPM_LIB=/usr/X11R6/lib
XPM_INC=/usr/X11R6/include/X11

#
# Fink OpenMotif
#
#MOTIF_LIB=/sw/lib
#MOTIF_INC=/sw/include

#
# DarwinPorts OpenMotif
#
MOTIF_LIB=/opt/local/lib
MOTIF_INC=/opt/local/include

Looking in the XDarwin directory there are three of the four .dylib  
libraries (libXm.dylib isn't there).

Does someone have an idea of why the compilation is failing? Is it due  
to the X11 not being the latest version? On my PowerBook I have  
XQuartz 2.4.0 installed, but the XQuartz project said there would be a  
separate release called 2.4.1 for Snow Leopard.

Thanks,
Bertrand
