To build universal binary, you need to configure like this:

   ./configure --disable-dependency-tracking \
       CFLAGS="-F$(FRAMEWORK_DIR) -isysroot $(SDK) -arch ppc -arch i386" \
       LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk -arch ppc -
arch i386"

FRAMEWORK_DIR is the path to the built framework - I use that for 
running the tests with the private framework. Maybe you don't need this.

Then call make like this:

   cd lib; make build -e -f libcurl.framework.make

This worked for 7.15.5.

For more info see http://developer.apple.com/documentation/Porting/
Conceptual/PortingUnix/compiling/chapter_4_section_3.html

You can also try to ask on the curl-library mailing list.
