Well, that's a bummer.

Unfortunately it doesn't work for Homebrew anymore and there seems to
be only one xsltproc in the system.

Fair enough.
I would appreciate it if you could help figuring out how to do this
for MacPorts, since I'm not a MacPorts user. I'll figure out how to do
this for Homebrew.
Does something like:
```
ln -s /opt/local/etc/xml/catalog /etc/xml/catalog
```
... work for you? Does your:
```
xsltproc --help
```
... also say that it uses /etc/xml/catalog path by default?
