Apple Mach-O Librarian (libtool) error with no specific error

I've had to deal with plenty of libtool errors previously, but I really don't know what to do with one that doesn't give me a hint.

Here is the full error:

I'm using the linker flags -lxml2 -ObjC -all_load

Any ideas as to what causes a exception-less libtool failure?

Oh, and I'm building a static library target. Previously, this was an app and I tore out all the unreusable stuff for the beginning of an app framework I'll be able to use.

I've had exactly the same problem yesterday and I found the solution. remove the -lxml2 from your other linker flags. It makes libtool link the library statically which causes problems.
