Arun,
I have the same setup FLTK-1.3, NXLIB (development head),
Nano-X (development head) with FreeType2 enabled.
If you are using Truetype fonts it may take a long time
to load the font for the first time, but after that it
is cached (if enabled). If TrueType, what version of
FreeType are you using. I am using FreeType 2.3.9
