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:

-rwxr-xr-x 1 root wheel 174228 Aug 30 16:55 libpq.so.2.1

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?
