building master on mac osx 10.7.3 with OSX 10.6 SDK

Hey guys I am trying to build master with the 10.6 SDK and I am running 
into issues in soltools. Below is the out put of make with debug symbols 
and additional debugging stuff enabled in my autogen.lastrun file.

autogen.lastrun switches

--with-macosx-sdk=10.6
--with-macosx-version-min-required=10.6
--with-macosx-version-max-allowed=10.6
--disable-mozilla
--without-doxygen
--without-system-libxml
--enable-debug
--enable-dbgutil

error with sol tools
