Looks like libsablot has some unresolved symbols.  Try running ldconfig and then do the make again.  And/or, supply the base directory where libsablot and libexpat are installed, during the ./configure of php.

This will explicitly tell gcc and friends where to find the required libs and header files.  If you installed things in the default location, trying using /usr or /usr/local
