Comment (by ryandesign):

 Looks like livecheck is broken because it was looking for .bz2 files and
 after 0.24.14 they switched to .xz, so that's an easy fix.

 It's using python27 because that's set by the waf portgroup. All versions
 after 0.24.14 have switched from waf to the meson build system so that's a
 bit more involved to fix. I'll see what I can do.
