I fear print(Sys.dlliist()) is not an option in julia. There's lots of
other options (Sys,MACHINE, Sys.init, etc) but no Sys.dllist().
My Julia install is Version 0.3.0-prerelease+308 if that is relevant :)
Also, nm /usr/local/lib/libsundials_cvode.so just gives me a long list like
this:
0000000000200e40 a _DYNAMIC
0000000000200fe8 a _GLOBAL_OFFSET_TABLE_
w _Jv_RegisterClasses
0000000000200e20 d __CTOR_END__

0000000000200e30 d __DTOR_END__

Thanks again
