[GRASSLIST:5822] Problem installing grass-6.0.0beta2

[David Adam]

Greetings!
I'm trying to install grass-6.0.0beta2 on a Fedora3 system, and the
configure
program stops with the error

checking for location of External PROJ.4 includes...
checking for proj_api.h... no
configure: error: *** Unable to locate External PROJ.4 includes.

The file was not part of the download; however, there is a file
named "gproj_api.h" in the include subdirectory.  Is this the file I
need?  Can I simply list the proj_api.h filename to that file?

Any advice is welcome...

Thanks!
