yes probably. Not sure about all the details, but you may want
to have a continuous build were missing symbols are not replaced.
In another SimpleITK discussion this time (http://review.source.kitware.com/#/c/20442/),
it seems that this also woks with gcc42 which is good for people building packages on older
OS X systems.
This blog post describing everything more in-depth was also found:
"On Linux, building with -shared tells the linker to ignore undefined symbols,
assuming that the dynamic linker will be able to resolve them at runtime.”
Using "-undefined dynamic_lookup” on OS X restores this behaviour.
Hope that helps.
