It looks like libagg is only available as a static library and not as a
shared library? If so, to link it into a shared library, it must be built
position-independent (-fPIC) on almost every platform except i386. This
error message, if libagg isn't PIC on any architecture, will likely result
in FTBFS on many architectures, such as amd64.
Ideally, libagg should provide a shared library. Otherwise, any package
that links against the existing library would require a rebuild for any
security vulnerabilities in the library.
Policy 10.2 covers this somewhat.
