these ports specify a hard dependency on openssl with "port:openssl".
I wonder whether this requirement can be relaxed to what e.g. lynx does:

	path:lib/libssl.dylib:openssl

This means a 'lib/libssl.dylib' needs to be present in $prefix,
and if it's not, it gets installed by installing openssl.
The point of specifying the dependency this way is that
some port other than openssl can already provide that library,
in this case typically libressl.

That's how I have e.g. lynx installed: install libressl,
then install lynx; it notices lib/libssl.dylib already exists,
and builds against that, instead of pulling in openssl to provide it.

Many other ports do it this way; the abovee ports are the exception.
That's why I want to find whether it works with them too.

I use none of these ports (but will try to do the full builds).
Could you, the users and maintainers, please test this with your port
and report success or failure here, or preferably at

I understand that fbthrift and folly in particular say in their Portfile
that a build against libressl fails, as of 2016-09-05.
Was there any progress in that?
