Garmin Ant Downloader (függőségi hiba?)

Nemrég szerencsésen hozzájutottam egy Garmin Forerunner 405 órához. Erről az adatokat sajátos módszerrel kell letölteni, a lényeg, hogy erre a csomagra van szükség hozzá: https://github.com/DanAnkers/garmin-ant-downloader

A csomagot letöltöm, kibontom, belépek a megfelelő könyvtárba, kiadom a make parancsot, mire a következő üzenetet kapom:

cc -g -Wall `xml2-config --cflags` -c -o gant.o gant.c

stb. (Az utóbbi sorok még sokáig ismétlődnek.)

Gondolom, valami függőségi probléma van, de arra nem jöttem rá, mit is kellene telepítenem.

Ubuntu 10.4

Előre is köszönöm!
