hi everybody,

I have installed boost (version 1.36) on my new mac and when I want to compile any program using parts of the boost library I have got the following error message (please, find below - "Undefined symbols...").
(remark: There is should be no problem with my own source code since it compiles fine on other systems.)

Did I forget to set some environmental variables or where does this error come from?
If anybody could help me with that it would be awesome.

Thanks a lot,
Judith
