Comment:

 The error message is correct. netpbm 10.69 will fail to build if netpbm
 10.68 is active. I reported this problem to the developer of netpbm, who
 said it is unfixable. This is not true, but it will take time to either
 convince the developer that it can be fixed, or fix it myself and send the
 fix to him. Rather than delay the release of new versions of netpbm in
 MacPorts until this is fixed, I added the `conflicts_build` portgroup to
 the port to detect the problem and advise you how to work around it, which
 is that you must deactivate your existing copy of netpbm before you can
 build the new one. If you have other ports installed that depend on
 netpbm, you must force the deactivation. In r130863 I have improved the
 error message that the `conflicts_build` portgroup displays to make that
 clearer, and to give an example of how to do that, so please `sudo port
 selfupdate` and then try again.

 Most users will not encounter this problem because the problem only occurs
 when building the port, and most users will receive pre-built binaries
 from our packages server. We don't have pre-built binaries for Mac OS X
 versions earlier than 10.6 which is why you did encounter the problem.
