[DRE-maint] Bug#741145: ruby-fcgi doesn't work with ruby1.8

[Satoru Takeuchi]

Source: ruby-fcgi
Version: 0.9.2.1-1
Severity: normal

Dear Maintainer,

* What led up to the situation?

  There is something bad in the transition from libfcgi-ruby1.8 to ruby-fcgi.

* What exactly did you do (or not do) that was effective (or
  ineffective)?

  1. run aptitude-safeupgrade to upgrade my system.

  2. Then libfcgi-ruby1.8 is replaced by the transitional package to ruby-fcgi.

  3. Run my web service (rails2.3 app) using lighttpd+fastcgi.

* What was the outcome of this action?

  Failed to launch the process for fastcgi with the following error log in fastcgi.crash.log.

* What outcome did you expect instead?

  Succeeded to launch the process.

* The result of my analysis.

  Although ruby-fcgi says that it replaces and provides libfcgi-ruby1.8, actually it seems not.
  There is no ruby1.8-related package in Depends section.

I confirmed this problem didn't happen after running the following steps.

 1. Uninstall ruby-fcgi.

    # aptitude purge ruby-fcgi.

 2. Get old (wheezy's) libfcgi-ruby1.8 from the following URL.

    # wget http://ftp.jp.debian.org/debian/pool/main/libf/libfcgi-ruby/libfcgi-ruby1.8_0.8.8-1_amd64.deb

 3. Install the old libfcgi-ruby1.8

    # dpkg -i libfcgi-ruby1.8_0.8.8-1_amd64.deb
