./configure, how to provide a different executable during the checking phase I am trying to install the MonoDevelop IDE from source. One of its prerequisites is Mono 2.10. Unfortunately the preinstalled mono runtime on my current Ubuntu system is 2.6.7. I managed to make a parallel mono install on my system. It is located at `/opt/mono-2.10`. Sadly, once I run the `./configure` script, it fails saying that the `/usr/bin/mono` executable is outdated (as well as other executables related to mono). I would want to try to pass a different path to `./configure`, to point to my parallel mono install (`/opt/mono-2.10/bin/mono`) etc. How can I do that? Thanks in advance.

Put `/opt/mono-2.10/bin` ahead of `/usr/bin` in your `PATH`:


PATH=/opt/mono-2.10/bin:$PATH
./configure
make


This may not be enough. Typically `configure` scripts take additional settings in the form of `--with-…` options or environment variables. Run `./configure --help` to see the possibilities.
