valac uses pkg-config to find out which compiler/linker flags to pass.
Check to make sure pkg-config is reporting the correct flags
(`pkg-config --libs --cflags`).  You'll either have to fix pkg-config or
pass the correct flags manually (using valac -X). The way to fix this
particular problem would be passing -X -I/usr/local/Cellar/gtk
+3/3.4.4/include/gtk-3.0 to valac, but you're likely to run into a lot
of similar issues, so I would advise you figure out what is going on
with pkg-config if possible.

Note that incorrect flags from pkg-config isn't really a Vala-specific
issue.  You should be able to get help from a forum for whatever you
used to install GTK+ on OS X, and you might have better luck there since
most people on this list are unlikely to be very knowledgeable about OS
X.
