Does the problem go away if the fontcap file is regenerated:
g.mkfontcap -o
?
If so, this would be an issue with the install procedure not generating 
the fontcap file to match the local system and the installation location 
of GRASS. But I think there is more to it than that. I seem to remember 
someone said was the problem was *not* that romans wasn't being set as the 
default, but that there wasn't a properly matching entry for it in the 
fontcap file. What does
d.font -L | grep romans
say?

In general for actually using the fonts, if the path to the stroke fonts 
given in fontcap is wrong, it doesn't matter, as the library code 
currently ignores it and reconstructs the path based on the current 
GISBASE. However, the code that scans the fontcap checks the path given 
for each font there to see if it exists, and skips it if not, so I suspect 
that might be where the problem is. If so, re-running g.mkfontcap to 
generate the proper paths should fix it. As should the following patch 
(untested) but that is a bit of a hack and I would prefer the issue to be 
resolved by making sure the fontcap is current.
