I have tried to install lxml on Mac OS X 10.6.2 using both

sudo python setup.py build --static-deps

and

sudo STATIC_DEPS=true easy_install lxml

In both cases I get

lipo: can't figure out the architecture type of: /var/tmp//ccdcpY3e.out
make[2]: *** [SAX.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
Exception: Command "make" returned code 2

What can I do to resolve this error?
