Distributing a binary version of GEOS (statically linked, in this case)
w/out distributing also the source code (of GEOS) is a clear license
violation.

Section 6 of the LGPL text cover this.
http://www.gnu.org/licenses/old-licenses/lgpl-2.0.html

If I recall correctly Apple forbids distributing source code trough
the apple store, which was the reason for VLC being dropped from there.
Apple devices are well known for being defective by design
