hyphen in path affects install scripte

If you decide to locate your civicrm codebase outside sites/all/modules (i.e. because you have multiple sites & multiple versions of civicrm) you CAN run the install script using

http://<your_drupal_home>/sites/<sitename>/modules/civicrm/install/index.php

UNLESS your sitename has hyphens in it. I am having to work around this by creating temporary symlinks with no hyphen.

NOTE that the presence or otherwise of location.settings.php doesn't seem relevant to this (ie. we had the same response before & after I put it there)
