mark-moseley/linecache — Issue #12: Not installable without becoming root

State: open

When using a Ruby that is installed system-wide (i.e., only writable as root), it is impossible to install linecache19 without becoming root. For example (the 1.9.1 you see all over the place is a quirk of Debian. It's actually Ruby 1.9.3):

```
[matijs@apricot] gem1.9.1 install --user-install linecache19
WARNING: You don't have /home/matijs/.gem/ruby/1.9.1/bin in your PATH,
gem executables will not run.
Building native extensions. This could take a while...
ERROR: Error installing linecache19:

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more
details. You may need configuration options.
