[GRASSLIST:2906] proj4 and grass57

[Michele]

Hi,

I have a problem with proj4 library, using debian3.0 and compiling grass57:

checking for location of External PROJ.4 includes...
checking for proj_api.h... yes
checking External PROJ.4 version... 445
configure: error: *** PROJ.4.4.6 or later is required.

I was trying to exclude proj4 use using the "--without-proj4 or --without-proj"
option but it doesn't work.
Anyone can suggest some fix for this?

thanks, Michele.
