We patch mochiweb a bit, to make it build on older versions of Erlang,
and to remove its dependency on the "crypto" application. I guess you
could live without these, but more importantly we also use a specific
version (basically what was the latest version at the point I started
writing rabbitmq-management) and haven't tested with newer versions.
If I were you I would add your patch to our set and build with our
wrapper. To do this, check out rabbitmq-public-umbrella, then check out
the mochiweb-wrapper repository within it:
(or run "make checkout" which will check out everything including
Then within mochiweb-wrapper add your patch, and add it to
WRAPPER_PATCHES in package.mk, then "make dist".
Alternatively you could build it yourself but I would try to use the
same version as we do - 9a53dbd7b2c52eb5b9d4 in the mochiweb git repo.
