Not sure how old that is, but just noticed that in

src/sage/structure/sage_object.pyx

two (actually just one, the second a consequence) doctests fail in case
FFLAGS happen to be set (and don't contain -fPIC).

Otherwise all tests (ptestlong) passed on Ubuntu 10.04.4 x86_64 (with
GCC 4.4.3; '-O3' and native).

It occurs on two different computers (two amd64 one with Debian jessie
and the other with Ubuntu).

Built w/o problems on OS X, 10.6.8 (Dual 6-core Xeons) and 10.10.3 (Quad-core Core i7). All tests ('ptestlong') passed on both systems!

FWIW, the 10.10 system's software update record shows both a completed update to Xcode 6.3 command-line utilities, and a pending update for the same (apparent) package. Anyone know what's up with that? Xcode itself is at 6.1 currently.

IMHO it wants to install XCode 6.3.1.

That could be, but the entry for the already-installed tools and the not-yet-installed version both say "command-line tools 6.3". Curious...

I have seen exactly this too.

For this version of XCode to be useful with Sage you will need
