Description

Hi, if I configure and install Erlang with a custom --prefix=/path/to/erlang, CouchDB's configure script finds `erl` and `erlc` from the environment, but it usually needs to be told about the location or erl_driver.h:

./configure --with-erlang=/path/to/erlang/lib/erlang/usr/include

It'd be nice if the configure script could check that location automatically, e.g. determining /path/to/erlang by stripping bin/erl off the path to `erl` that it found earlier.

Alternatively, I think --with-erlang ought to be modified to take the path to the base of the Erlang installation, rather than the exact path to the location of the folder containing erl_driver.h. Best,

Adam
