`gem install ...` broken after install

[Samuel Cochran]

After installing and performing $(gel shell-setup), running gem install mailcatcher or anything similar simply hangs. Additionally, any binaries previously installed by gems fail with something like:

===== Gel Internal Error =====

Traceback (most recent call last):
	1: from /usr/local/rbenv/gems/2.6.0/bin/mailcatcher:23:in `<main>'
/usr/local/Cellar/gel/HEAD-40287c8/lib/gel/compatibility/rubygems.rb:159:in `activate_bin_path': Unknown gem "mailcatcher" (RuntimeError)

Hmmm.

running gem install mailcatcher or anything similar simply hangs

That's supposed to work -- gem should load https://github.com/gel-rb/gel/blob/master/lib/gel/compatibility/rubygems/gem_runner.rb

any binaries previously installed by gems fail

That's expected: after shell-setup, Gel is responsible for all gem loading, and the gem isn't installed. To fix it easily you'd need a gel install <gem-name> (#58), so unfortunately the simplest solution right now is to create a temp dir, put a one-line Gemfile inside, and then gel install. 🙈

I found gel install-gem mailcatcher (I'm running gel master), but it only installs the gem itself, not any dependencies:

gel install-gem mailcatcher

I'm actually not sure when install-gem learned to include dependencies, but it does work now:

$ gem install --pre gel
