MapScript projection error - CGI works fine

[Pascal Ehlert]

Hi Mapserver Community!

This is my first post here, I hope the project is still active.

I've just been trying to migrate my MapServer stuff from the CGI version to
the Ruby MapScript version
for better integration with my Rails (for those of you who don't know, it's
a Ruby web framework) application.

Now, while CGI is working fine, the MapScript refuses to work at all,
because of a projection error.
This really confuses me, I'm using exactly the same mapfile for both of them.


This is what I do in Ruby and the error I get:

-- 
irb(main):001:0> require "mapscript"
=> true
irb(main):002:0> include Mapscript
=> Object
irb(main):003:0> map = MapObj.new("/var/www/map/moz_serv/moz.map")
RuntimeError: loadProjection(): Projection library error. Projection support
is not available.
-- 


And here comes my mapfile.. I know it's not perfect and actually it wasn't
even me who created it, but at least it works with CGI.
