ruby-build output (tree)

(In reply to Michael Moll from bug #202999, comment #4)

Could rbenv or rvm's shell sourcing scripts interact with building gems?

I would assume that bsd.ruby.mk would workaround that. I haven't tracked down a prior dialog on this.

This problem could be difficult to diagnose unless the bug submitter detailed they were using this tool.

bsd.ruby.mk seems to look for ruby (as a last resort) in /usr/local/bin/ruby.

In the case of the parent topic, ruby-build (a tool used in unison with rbenv) does two things:

1. Can build ruby by itself, `ruby-build 2.2.2 /usr/local` could overwrite ruby. It would be like building ruby from outside the port and installing it there.

For kicks, I attached what a `ruby-build 2.2.2 ~/ruby` would output. See attachment for output tree.

From this, it looks like it would trash the ruby installed from the system. `pkg-check(8)` would probably go off.

2. It is used by rbenv (giving the rbenv install command) and installs the ruby to ~/.rbenv.

As for environmental variables from rbenv/rvm mangling into port building - I would assume no unless we see issues otherwise.  If ruby gems are getting odd build errors that defy explanation - asking them if they use rbenv/rvm may be pertinent.

To give it a shot, I gave devel/rubygem-ffi a try in rbenv:

$ cd /usr/ports/devel/rubygem-ffi

tony at z600 in /usr/ports/devel/rubygem-ffi 
$ ls
Makefile  distinfo  pkg-descr

tony at z600 in /usr/ports/devel/rubygem-ffi 
$ rbenv which ruby
/usr/home/tony/.rbenv/versions/2.2.2/bin/ruby

$ ruby --version

$ sudo make

RubyGems installed the following executables:
	/usr/ports/devel/ruby-gems/work/stage/usr/local/bin/gem21

Ruby Interactive (ri) documentation was installed. ri is kind of like man 
pages for ruby libraries. You may access it like this:
  ri Classname
  ri Classname.class_method
  ri Classname#instance_method
If you do not wish to install this documentation in the future, use the
--no-document flag, or set it as the default in your ~/.gemrc file. See
'gem help env' for details.
