Having stuff in /usr/local commonly makes messes, and is not supported.

In this case, your problem is probably that the shell caches where it saw
an executable.  "which" is not built into your shell, apparently, and/or is
not able to use your interactive shell's cache --- so it sees the first one
in $PATH.

"hash -r" (Bourne-like shells) or "rehash" (csh-like shells) will flush and
recompute the path cache.
