cat $GISBASE/etc/freetypecap | awk -F: '{print $2}' | sed 's!/[^/]*$!!' | uniq -c | sort -nr | head -n 1 | cut -c 9-

Actually, it should check for $GRASS_FT_CAP, and only use
$GISBASE/etc/freetypecap as a fallback.

If you wanted to bypass freetypecap altogether and scan the
directories yourself:

for dir in ... ; do
    if [ -d "$dir" ] ; then
        find "$dir" -type f -iname '*.ttf' -print
    fi
done | sed 's!/[^/]*$!!' | uniq -c | sort -nr | head -n 1 | cut -c 9-

If you wanted to do it entirely in Tcl, you would need to perform
directory traversal, as the actual font files will frequently be in
subdirectories of the standard font directories.
