Fancy in linear projections
The fancy MAP_FRAME_TYPE should work also for linear projections, but it doesn't. Is there a reason for that, or simply it was never implemented?
gmt psbasemap -R0/100/0/100 -Ba -P -JX10 --MAP_FRAME_TYPE=fancy > lixo.ps

Well, we do censor things to avoid the user doing stupid things in GMT and make us look lame. For instance, we resist users who wish to label maps with gratuitous "longitude" and "latitude" labels. The checker board frame is only ever used for geographic maps. Of course, you can turn your Cartesian data into geographic by appending "d" to the -J option but only if your data range is within geographic limits, e.g.
psbasemap -R0/30/0/30 -JX5id -P -Baf > t.ps
works fine for fancy frame while
psbasemap -R0/30/0/300 -JX5id -P -Baf > t.ps
will tell you a thing or two about latitudes.
