If you still have the build tree around, do rm -rf sparc-sun-solaris2.9/boehm-gc sparc-sun-solaris2.9/sparcv9/boehm-gc make all-target-boehm-gc If this still yields an error, try to do a full build after configuring with an absolute path to the source directory (as recommended in the documentation).
