Yes, Subsurface doesn't build out of the box with Qt4 anymore. I have a
patch that fixes that, but I don't have an elegant way to have both work
at the same time. Everything (except Ubuntu 12.04) is build with Qt5 now.

The INSTALL file should have that. I am on Fedora 20 here building with
Qt5 and it works without a problem.

Hmm, that sucks. This used to work. I test installed the packages from the
repository on a clean VM.

4.3-22.1 --- hmm, that's odd. Where did you find that? That's quite old
and I worry if we offer that somewhere.

The quickest way should be to install the things that we have in the
INSTALL documenent for Fedora and build from source. But I really need to
investigate what's up with libgit2 and why it isn't pulled in with the
repository... but doing that from Fiji seems like a stretch. Internet here
is great for a dive destination, but not all that great compared to what I
have at home :-)
