The comments at the end of 339 indicate that I could not get it to work:

The patch does not work - it seems there is a darwin-specific patch to the config file in the dist directory which I can't make head nor tail of. Perhaps you can take a look?

I think Erik wrote the darwin-specific patch.

- From the comments in the ticket, it looks like setting OPENSSL_DIR worked for me.  It might be that I was not using any thorns which actually needed OpenSSL, so simply setting the variable would stop the OpenSSL configuration script complaining, and the rest of the build would work correctly because openssl was not needed.

Correct - 339 did not work even when I wrote it, as I indicated in the comments.  342 worked when I wrote it, so it just needs to be reviewed and then hopefully applied, but it won't solve any problem without a working implementation of 339.  I have just changed the status of the patch to "Review" (this status was not available when I opened the ticket).
