Either you upgraded to Snow Leopard, or migrated to this Snow Leopard machine from a different machine, and did not perform the Migration procedure, or you subsequently installed a 3rd-party package that itself was built using MacPorts which overwrote MacPorts-installed files like your zlib library. In any case, the solution to this specific issue is to rebuild your zlib:

sudo port -n upgrade --force zlib

However, in either of the above scenarios, it's likely other libraries are affected as well, so you should probably uninstall and reinstall MacPorts and all ports.

Rebuilding zlib did not fix the problem.

How do I "uninstall and reinstall Macports and all pots" as suggested?

Thanks.

[jnandigam@…]

Uninstalled macports, reinstalled it, and installed ruby19. Everything is fine.

Thanks.
