MapScript projection error - CGI works fine

[Pascal Ehlert]

Hi Frank!

I figured that out myself in the meantime, I used the mapserver from the 
debian package
and compiled mapscript on my own.

As Ruby mapscript isn't very well documented and I didn't check the 
whole sourcecode yet,
does anyone know how up-to-date it is?
Are at least the current main features supported?


Thank you (especially Frank for your help of course)

Pascal
