There are some ports that don't compile, and obviously there will be a
few that do compile, but fail to run correctly. Diagnosing the causes
is always an interesting venture, you encounter the most diverse
See https://wiki.freebsd.org/PortsAndClang for an overview, though some
of the instructions are outdated, now clang is the default compiler.
Of special interest are the results from the build cluster, where you
can get a quick overview of which ports don't build, and how many other
ports depend on them.

I don't use Gnome, but Xorg builds just fine with clang, and runs
without problems for me. Regarding Gnome, and/or other big frameworks,
it is probably best to ask around on the freebsd-ports mailing list,

That depends, if the port is easy to fix (borked configure scripts are
VERY common), then just fix it. Only if the port is extremely tightly
coupled to gcc, or even a very specific gcc version, then use USE_GCC.
