[PD-dev] [ pure-data-Patches-1378927 ] OSX/pd 0.39: fix for loading externals using static libs

[Thomas Grill]

Hi Jamie,
thanks for the explanation, but the it's a fact that NsLinkModule is 
still in Miller's version and it would be very interesting to know 
whether NSLINKMODULE_OPTION_PRIVATE can be re-included without 
disadvantages.
As it is now, it's a real blocker for flext-based externals.

all the best,
Thomas
