John,

This may be off base, but based on my recent experience upgrading to  
Snow-Leopard (10.6), here are some observations:

1. The hcp version of gfortran is built against the 32 bit (OSX 10.5)  
gcc compilers.  This could be why you are getting the 10.5 libraries  
brought in from /usr/lib.  You will likely not have any success mixing  
the Apple 10.6 SDK with this version of gfortran (at least I did not).

2. I had to "roll my own" version of gfortran.  Actually, I did this  
through fink (http://www.finkproject.org) which I installed as the 64  
bit version of fink.  A few weeks ago when I last checked there were  
no binaries for gfortran on 64 bit, so I used fink to compile the  
entire gcc/gfortran suite.

3. To avoid conflicts between apples SDK versions of gcc and the ones  
compiled via fink, I point to the fink versions first.

I haven't yet tried trilinos 10 with my new system.  If I get the  
chance in the next little while I will let you know what I find.
