Hi,
  sorry for such a late response.
  I downloaded the CVS version of GRASS GIS and compiled it on my debian
sarge machine. I then used the commands given by you to create a sample
vector and displayed it on monitor. For the example that you have in your
snapshot, it works fine. But then I realised that you have displayed a
string in devanagari/hindi which does not require any processing on font
side. i.e. the text is displayed just similar to english text
 using juxtapositioning of glyphs. So I tried with some conjunct text which
requires some positioning/replacement rules to be used from the opentype
font, it couldnot display properly. See the snapshot for details (snapshot
uploaded on http://203.199.16.202/grass_cvs_comparison.png ). The left
monitor show the GRASS CVS version as downloaded on 2006-01-05 and compiled
as-it-is. The right monitor shows output of d.tect.freetype compiled with
Indix2 libraries. The right monitor show properly rendered text while the
left monitor show text in form of  juxtapositioned glyphs. I knew that
because of freetype library GRASS will be able to use opentype fonts but I
also knew that it doesn't have any rendering engine like pango/qt/indix2 to
render complex text in indic scripts correctly.

We had tried this same thing in past without any rendering engine and
failed. That is why I had filed this bug (
http://intevation.de/rt/webrt?serial_num=3189 ). I must apologise for not
following it up properly.

regards
