perhaps this (or if modifications are required, some variation) can be incorporated into the CairoRelease twiki will then work on macs "out-of-the-box" to the same degree as other unix platforms.

I'd rather not take this last minute change into Cairo for two reasons:

1. Extra runtime processing that can be avoided (-X is expensive)
2. MartinGregory's UpgradeTWiki script probably needs to be changed
