Just downloaded and installed MacPorts 1.5 and ran:

sudo port install boost

The download completed and the build seemed to execute without a problem.

Next, I tried:

man boost -> failed, no entry found

locate boost -> libs found in various places, usr/include/... , /Developer/SDKs/.../bits/ which boost -> failed apropos boost -> failed (nothing appropriate)

Any ideas on what could be going wrong? Thanks!
