make gsweb

[Elim Qiu]

After installed GSWeb, I tried to build hello wo-app but I got this

This is gnustep-make 2.4.0. Type 'make print-gnustep-make-help' for
help.
Making all for gswapp Hello...
 Creating Hello.gswa/....
 Compiling file Hello_main.m ...
 Compiling file Hello.m ...

make[2]: *** [Hello.gswa/./Hello] Error 1
make[1]: *** [Hello.all.gswapp.variables] Error 2
make: *** [internal-all] Error 2

=================================
Looks like make couldn't find the frameworks. But the path is supposed
to be altered everytime some new module is installed.. 

Anyway, how to fix this? Thanks
