Nope:

bash-3.2$ file /opt/local/lib/libexpat.dylib
/opt/local/lib/libexpat.dylib: Mach-O dynamically linked shared library i386

If it helps any I'm running Mac OS X 10.6.1, and what I'm trying to do
is compile the libexpat library as x86_64 to satisfy some macports
dependency requirements that it can't on its own resolve. When I ls
the /opt/local/lib directory I see that the only changes made after I
install libexpat is the libexpat.a and libexpat.la files:

bash-3.2$ ls -lah /opt/local/lib/libexpat*
lrwxr-xr-x  1 root  admin    16B Nov 30  2008
/opt/local/lib/libexpat.0.dylib -> libexpat.1.dylib
-rwxr-xr-x  2 root  admin   143K Nov 24  2007
/opt/local/lib/libexpat.1.5.2.dylib
lrwxr-xr-x  1 root  admin    20B Nov 30  2008
/opt/local/lib/libexpat.1.dylib -> libexpat.1.5.2.dylib
-rw-r--r--  1 root  admin   242K Oct  4 14:09 /opt/local/lib/libexpat.a
lrwxr-xr-x  1 root  admin    20B Nov 30  2008
/opt/local/lib/libexpat.dylib -> libexpat.1.5.2.dylib
-rwxr-xr-x  1 root  admin   743B Oct  4 14:09 /opt/local/lib/libexpat.la

But I need the libexpat.dylib file to be made x86_64, how do I do
this? Is this something special to Mac OS X that requires a special
routine to accomplish? Thanks!
