That's right. I should have qualified what I said by stating this
strategy only works for ports which depend on the various tex
executables. Because Tex Live does not install any libraries, you
cannot satisfy dvipdfmx's dependency on libkpathsea through TeX Live.
I don't know if gwtex installs libkpathsea, but if it does you could
avoid installing macport's tetex by using the library there. You could
do this by editing the dvipdfmx port file (sudo port edit dvipdfmx)
and change the line "lib:libkpathsea:teTeX" to
"path:/path/to/libkpathsea:teTeX" (without the quotation marks). You
might then have to update the Portindex file:

sudo portindex /opt/local/var/db/dports/sources/rsync.rsync.darwinports.org_dpupdate_dports/PortIndex

(The above should all be on one line.) I haven't actually tried this
so I'm not certain if the portindex step in necessary or if there's an
easier way to do it, but the above should work.
