Enter an interactive shell for Homebrew's build environment. Use years-battle-hardened
|
|
build logic to help your `./configure && make && make install`
|
|
and even your `gem install` succeed. Especially handy if you run Homebrew
|
|
in an Xcode-only configuration since it adds tools like `make` to your `PATH`
|
|
which build systems would not find otherwise.

Your shell has been configured to use Homebrew's build environment;
|
|
this should help you build stuff. Notably though, the system versions of
|
|
gem and pip will ignore our configuration and insist on using the
|
|
environment they were built under (mostly). Sadly, scons will also
|
|
ignore our configuration.
|
|
When done, type `exit`.
