[Xastir] Serial GPS support in Xastir built from Darwin Ports?

[Bernard Michael Tyers]

Hi all,

I have been listening for a while on the list, and managed to get
Xastir running nicely (after a fresh install) on my PowerBook (PPC
CPU) running Mac OS X 10.4.9 (kernel Darwin 8.9.0 if its important) by
installing it from Darwin ports (following
http://www.xastir.org/wiki/index.php/Darwinports steps).

>From the Darwin steps, I can't tell if it gives GPS support. The
startup of Xastir gives:

oberena:~ Bernard$ /usr/local/bin/xastir


Built-in map types:
      gnis   USGS GNIS Datapoints
       map   APRSdos Maps
       map   WinAPRS/MacAPRS/X-APRS Maps
       pdb   PocketAPRS Maps

Support for these additional map types has been compiled in:
       geo   Image Map (ImageMagick/GraphicsMagick library, many
formats allowed)
       geo   URL (Internet maps via libcurl library)
       shp   ESRI Shapefile Maps (Shapelib library)
       tif   USGS DRG Geotiff Topographic Maps (libgeotiff/libproj)
       xpm   X Pixmap Maps (XPM library)
       tab   MapInfo TAB
       mid   MapInfo MID
       mif   MapInfo MIF
       ddf   Spatial Data Transfer Standard (SDTS)
       rt1   US Census Bureau TIGER/Line
       s57   International Hydrographic Organization (IHO) S-57
       dgn   MicroStation DGN

which doesn't really tell me about GPS support. So I am guessing it doesn't.

Can anyone point me in the direction of how to get support for my
serial GPS (connected via a Keyspan Serial-USB converter). Its a
Garmin eTrex model (the old yellow cased, monochrome display).

thanks in advance.
