Such questions are more appropriate on the Mac-SIG list.

I just installed openNLP with dependencies on an R64 system using the  
64 bit GUI Installer. The number of dependincies was fairly extensive  
so it took some tme:

Warning: dependency ‘Rgraphviz’ is not available
also installing the dependencies ‘ellipse’, ‘mboost’, ‘ape’,  
‘flexmix’, ‘rmeta’, ‘kernlab’, ‘multcomp’, ‘HSAUR’, ‘gclus’,  
‘colorspace’, ‘modeltools’, ‘coin’, ‘vcd’, ‘ipred’, ‘cba’, ‘party’,  
‘slam’, ‘filehash’, ‘proxy’, ‘RWeka’, ‘Snowball’, ‘XML’, ‘rJava’,  
‘tm’, ‘openNLPmodels.en’, ‘openNLPmodels.es’

It loads without error.
