I just checked and HFST works just fine here. Looking at 
src/morphology/AnalyzerFactory.cpp where this error comes from I can only see 
two possible explanations:

1) For some reason code inside #ifdef HAVE_HFST is not compiled. You can check 
this by writing some invalid C++ inside the block and see if the code still 
compiles or not.

2) dictionary.getMorBackend() does not return string "hfst". Maybe your 
voikko-fi_FI.pro contains a typo or it has been edited on OS X where some 
strange control characters may get inserted at the end of line. Or maybe the 
C++ code that reads this file behaves differently on OS X. What do the 
following commands print?

 cat ~/.voikko/2/mor-hfst/voikko-fi_FI.pro

 md5sum ~/.voikko/2/mor-hfst/voikko-fi_FI.pro
