I followed the instructions from here:
http://www.boost.org/doc/libs/1_40_0/more/getting_started/unix-variants.html#prepare-to-use-a-boost-library-binary

and it spent a bunch of time compiling everything.  no errors.  yay.

so then i go to link my program, i added <boost dir>/stage/lib/ 
libboost_thread.a to my project, cuz that's how you static link,  
right?  where <boost dir> is the location of the boost installation

but it says:

<boost dir>/bin.v2/libs/thread/build/darwin-4.2.1/release/threading- 
multi/libboost_thread.dylib, file is not of required architecture

Undefined symbols:
     <long list of all the boost symbols i used>

interesting that even by adding the .a file, it went and found the  
dylib?  is that normal?  anyway, wrong architecture??  how do i make  
it build universal?  (PPC plus intel?  and what's with the missing  
symbols?

i'm not really a n00b, i just appear to be one today.
