ruby compiled w/o readline support

[martinpovolny]

platform rhel6.2
steps to reproduce:

export RBENV_VERSION=1.9.3-p362; curl https://raw.github.com/aeolus-incubator/dev-tools/master/bootstrap.sh | /bin/bash -x

then initialize rbenv

go to conductor/src

run bundle exec rails c

get:
[root@hp-magnycours-02 src]# bundle exec rails c
===== boot.rb will try and use bundler =========
/root/.rbenv/versions/1.9.3-p362/lib/ruby/1.9.1/irb/completion.rb:9:in require': cannot load such file -- readline (LoadError) from /root/.rbenv/versions/1.9.3-p362/lib/ruby/1.9.1/irb/completion.rb:9:in<top (required)>'

extra info: on fc17 the readline is there

So the fix is to the readline package in bootstrap.sh's dependencies, right? Want to make sure I'm not missing something...

[martinpovolny]

Sorry, I did not provide any fix. I just filed the bug so that it's not forgotten. The libreadline-dev (or how it is called on RH/Fedora) was installed yet the rbenv-compiled ruby was lacking the readline.

I did not dig deeper then checking that the bug is NOT on fc17 so it might be a RHEL{whatever version} specific problem.

Don't know if this should be considered a high/low priority either. Was low priority for me at the moment of filling it.

I noticed when I rebuilt ruby on F18 that it didn't pick up readline support for irb, even though I have readline-devel installed. I haven't had a chance to investigate further, but it's a data point for you.

[martinpovolny]

@jeckersb thanks for the input, so we have at least one RHEL and one Fedora not picking it

can you provide more information? what did you use rbenv? rvm? did you run dev-tools?

[jeckersb]

My case was rbenv, I just downloaded the ruby tarball (1.9.3-p362) and build it manually. No dev-tools involved.

I just did a config/make/make install from clean source, and now I have readline support as expected. Weird, no clue why it was broken before.
