I think that several folks have articulated the many valid reasons why traditional static libraries are desireable: organization/ modularization of code within a single project by team members, use of large third party (often open source) in situations where one wishes to use a particular snapshot of the library - not as a dynamic "system resource".
All this can be done with dylibs on MacOS X. See below

It can NOT all be done with dylibs. One point for a static lib in an product is support cost. You get the same behavior for calls into that lib *all the time*, even across OS platforms, and not some hard reproducible support call because user installed rev x.y of that .dylib by the means of dports et al. If you include _your_ private snapshot of that library as .dylib in you app, chances are you loose diskspace - with a dylib there is no chance the linker can strip e.g. most of the libtiff code because it is only used to embed an color profile tag into DNG files.

They are not needed. So Apple tools like Xcode don't support them. You can use them as long as you stay inside the ./configure/ make/make install build method.

Oh yeah, we need FAAAAAAAAAAAAAAAAAAAAAT binaries are default, and they will bloat even more for two architectures. Striping unused function calls is really some undesirable luxory for those cheap folks that don't "want" to have 4 GB RAM and 250 GB drives in their Laptop. Static libs are the luxory for those cheap developers that don't want to pile one machine per OS X subrevision, security update and processor architecture in order to reproduce exact behavior at the hotline.

Mind to specify the meaning of "not needed" in an commercial environment?
