Hi,
	Correct, you don't have to remove -shlibs, because those are
*install* depended-upon by other packages as dynamic shared libraries.
the readline5 package you removed was the *static* library, which doesn't
have to stay around because other libraries basically copy what they need
from it when they link against it.

One thing, before you just run 'make' again, you should re-configure
because the absence/presence of readline5 will affect the outcome of
"config.h", which is included (directly or indirectly) by everything.  (If
you configured with cache '-C', remove config.cache first too.)
"./config.status --recheck && config.status" will re-run configure using
the same parameters you passed the first time.

Ok.  To summarize:
To compile/link against packages in fink, be it readline or other library,
one should just pass CPPFLAGS="-I/sw/include" LDFLAGS="-L/sw/lib"
to configure before making.  (Replace 'sw' with whatever your fink-root
is.)
