It stands for "multi-threaded".

Then I guess Ubuntu only offers the single-threaded versions of boost.

Boost can be installed in both single- and multi-threaded versions simultaneously, but they must be built separately; the boost port defaults to no_single to cut the build time in half.

If their source assume that the single-threaded versions of boost exist, but would also work with the multi-threaded versions, then you could edit the source to add the "-mt" suffix.

Or you could install the boost port without the default +no_single variant. However that's not ideal because that would require everyone wanting to use your port to rebuild boost that way.

A better solution for the boost port would be for single- and multi-threaded versions to be in separate simultaneously-installable subports.
