 Replying to [comment:1 neteler]:
 > Can you please attach the PROJ_INFO file? And, if known, the EPSG code?

 Sure, but I think the issue is a generic one, not specifically linked to
 this case.

 The PROJ_INFO of the .pack file corresponds to EPSG31370:


 {{{
 name: Belge 1972 / Belgian Lambert 72
 datum: bel72
 ellps: international
 proj: lcc
 lat_1: 51.16666723333333
 lat_2: 49.8333339
 lat_0: 90
 lon_0: 4.367486666666666
 x_0: 150000.013
 y_0: 5400088.438
 no_defs: defined
 }}}

 And here's the PROJ_INFO file of the location:


 {{{
 name: Lambert Conformal Conic
 proj: lcc
 datum: bel72
 ellps: international
 lat_1: 51.16666723333333
 lat_2: 49.8333339
 lat_0: 90
 lon_0: 4.367486666666666
 x_0: 150000.013
 y_0: 5400088.438
 no_defs: defined
 }}}

 I don't remember how this location was created (based on a file, perhaps),
 but as you can see the parameters are strictly identical, it's just the
 name that differs.

 v.unpack uses compare_key_value_text_files from lib/python/script/core.py.
 Maybe a solution would be to add to that function a list of keys to skip
 and then v.unpack could add 'name' as a key to skip. Thus, if all other
 parameters are equal the projection test wouldn't fail.
