| Subject: | Makefile.PL should better behave on systems without ruby |
If no ruby is installed at all, then a Makefile.PL run looks like this:
...
Found these ruby executables on your PATH:
Use which? [1]
Invalid number. Please enter only numbers from 1 to 0 or the full path to your ruby executable.
Set the INLINE_RUBY_EXECUTABLE environment variable to the full path to your ruby executable to avoid this question.
...
Probably it's better in this case do not show the prompt at all.
