libQuantLib.la is ok, but it's just a stub referring to the actual library file which should be in the same place. How did you build QuantLib?

You'll need to find out where you installed the QuantLib C++ library, libQuantLib.so . On Linux systems, it would be in /usr/local/lib; there's a chance that the location is the same on your Mac, too.  Once you have found the library, you need to add its location to the dynamic linker path DYLD_LIBRARY_PATH; see for instance <http://superuser.com/questions/282450/where-do-i-set-dyld-library-path-on-mac-os-x-and-is-it-a-good-idea>.

Ok I applied steps that you suggested. I think it works. 

The I tried to import QuantLib as ql in IPython , I get this error message:

ImportError: dlopen(//anaconda/lib/python2.7/site-packages/QuantLib/_QuantLib.so, 2): Symbol not found: __ZN8QuantLib10DateParser14parseFormattedERKSsS2_
  Referenced from: //anaconda/lib/python2.7/site-packages/QuantLib/_QuantLib.so
  Expected in: dynamic lookup

I apologize to bother you, but I really would be able to solve the problem.

Thank you in advance,

Stefania
