to solve the problem, we shall do "sudo aptitude install libgs-dev"

Steps to reproduce:
in svn trunk directory

1. autogen.sh (do not remind any lack of dependency)
2. make
3. fail with the above "msg"

* make sure haven't install libgs-dev, otherwise the compilation will pass 


Actual results:
compilation failed

Expected results:
compilation sucessful

Does this happen every time?
yes, if you don't install the dependency.

Other information:
nothing else.
