[Rivet] siscone-spherical not found

[James Monk]

Hi,

When I try to load the Rivet module rebuilt against the new Fastjet  
2.4 I get a symbol not found error:

	ImportError: dlopen(/usr/local/lib/python2.5/site-packages/_rivet.so,  
2): Symbol not found:  
__ZN17siscone_spherical11CSphsiscone12compute_jetsERSt6vectorINS_12CSphmomentumESaIS2_EEddidNS_18Esplit_merge_scaleE 
  Referenced from: /usr/local/lib/libSISConePlugin.0.dylib

It looks to me like there is a missing shared library - I see  
libsiscone.dylib but no libsiscone_spherical.dylib.  I do see  
libsiscone_spherical.la and .a and libsiscone.dylib.

Has anyone else seen this?  Has anyone tried the new FastJet on OS X ?

James
