[Tracker] Problem building tracker

[Charles McCreary <charles mccreary crmeng com>]

I grabbed the latest from the svn repository (892) and I'm having a 
little trouble building it. I'm running Ubuntu Feisty and the build 
fails with:
gcc -Wall -Wchar-subscripts -Wnested-externs -Wpointer-arith 
-Wsign-compare -o tracker-extract tracker-extract.o 
tracker-extract-oasis.o tracker-extract-ps.o tracker-extract-pdf.o 
tracker-extract-abw.o tracker-extract-png.o tracker-extract-mp3.o 
tracker-extract-exif.o tracker-extract-msoffice.o 
tracker-extract-imagemagick.o tracker-extract-mplayer.o 
tracker-extract-totem.o tracker-extract-html.o tracker-extract-xmp.o  
/usr/lib/libglib-2.0.so -lpng12
tracker-extract.o: In function `main':
tracker-extract.c:(.text+0xd5e): undefined reference to `g_thread_init'

Relevant libraries in /usr/lib:

/usr/lib/libgthread-1.2.so.0       /usr/lib/libgthread-2.0.la    
/usr/lib/libgthread-2.0.so.0.1200.11
/usr/lib/libgthread-1.2.so.0.0.10  /usr/lib/libgthread-2.0.so    
/usr/lib/libsgthreads.so.0
/usr/lib/libgthread-2.0.a          /usr/lib/libgthread-2.0.so.0  
/usr/lib/libsgthreads.so.0.3.10

Yet there is not a -lgthread nor a /usr/lib/libgthread-2.0.so in the 
build. Is there a configuration switch I should be using or should I 
force it?
