tcl on Mac OS X

I've been experimenting with Mac OS X lately and would like to get 
pgaccess running on it.  The database itself is on another machine, but  
I built the libpq and libpgtcl interfaces on OS X and installed them to 
/usr/local/pgsql/lib.  The version of tcl that comes with OS X doesn't 
support dynamic loading, so I rebuilt tcl/tk 8.3.3 with a patch that 
enables dynamic loading on OS X.  After installing that, I downloaded 
pgaccess and gave it a shot...and I got the following error message:

Error in startup script: dyld: permission denied    while executing
"load libpgtcl[info sharedlibextension]"    (procedure "main" line 3)    invoked from within
"main $argc $argv"    (file "/usr/local/pgaccess/main.tcl" line 249)

I'm not quite sure what that means...my only guess was the permissions 
were wrong on either libpq or libpgtcl, but they look ok to me:

I'm in XDarwin when I'm running it, so it shouldn't be an X Windows 
related problem.  Does anyone else have any ideas?
