my apologies for cross-posting.
I just compiled Gebabbel 0.3 successfully for a Nokia N810. The binary is
available on sourceforge. There's no installer, so you first need to
manually install gpsbabel and Qt4. Then download the Gebabbel archive
for Maemo and extract it. You need to manually install three files into some
magic system folders. See the file INSTALL.txt for the correct locations.
I hope it is useful.
