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';

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.
