It's not possible to install mapnik on debian sarge, as the libboost
libraries are too old. However, this problem is probably not that:
either you are missing the boost_thread dev library, or you are having
the same problem that I am, which is that gcc3.3 doesn't seem to build
with -pthread support by default (while later versions do?) 

I modified line 73 of scons/scons-local-0.96.1/SCons/Tool/c++.py:

     env['CXXFLAGS']   = SCons.Util.CLVar('$CCFLAGS')
-    env['CXXCOM']     = '$CXX $CXXFLAGS $CPPFLAGS $_CPPDEFFLAGS
     $_CPPINCFLAGS -c -o $TARGET $SOURCES'
+    env['CXXCOM']     = '$CXX $CXXFLAGS $CPPFLAGS $_CPPDEFFLAGS
$_CPPINCFLAGS -pthread -c -o $TARGET $SOURCES'
     env['SHCXX']      = '$CXX'

This allowed my build to succeed. 

I don't know what this means with regard to your problem, but I was
having a similar problem and was able to solve it this way.
