Nice!  I did this:

pkg install lang/clang-devel
export PATH=$PATH:/usr/local/llvm-devel/bin
scan-build cc a.c

scan-build: Using '/usr/local/llvm-devel/bin/clang' for static analysis
a.c:10:10: warning: Use of memory after it is freed
    a[5] ='b';
    ~~~~ ^

scan-build: 1 bug found.
scan-build: Run 'scan-view /tmp/scan-build-2015-02-16-211517-60875-1' to

It looks like some stuff for scan-view is missing from the port.  Do you
have any
ideas offhand what is missing?  It's not so important, because the
results of scan-build can be opened up in any web browser, independently of
scan-view.

Would it be possible to include scan-build somwehere under
/usr/src/contrib/llvm
in the FreeBSD source tree?  It seems like it is handy to have.
However, if it is better to only have it in the port and not in src, I
understand.
