The default rule for a module attempts to build the HTML
documentation, which involves running the program with the
--html-description flag to obtain the module/option/flag descriptions. 

Running the module requires that GISRC is set and refers to a file
containing settings for at least GISDBASE, LOCATION_NAME and MAPSET. I
don't recall whether those values need to be valid, or just exist.

The rule sets GISRC from RUN_GISRC, which is defined as:


You can either copy the demolocation directory from the source tree,
or just change the value of RUN_GISRC to point to a suitable file.
