cdo-1.7.0 fails to build on Mac OS X 10.6.3

[yurukc]

Actually I was trying to install python34 but at the end it gave following error.

---> Cleaning python34
---> Updating database of binaries
---> Scanning binaries for linking errors
---> Found 4 broken file(s), matching files to ports
---> Found 3 broken port(s), determining rebuild order
---> Rebuilding in order

cdo @1.6.4
grads @2.0.2
pcre @8.35

---> Computing dependencies for cdo
---> Building cdo
Error: org.macports.build for port cdo returned: command execution failed

Then I tried "sudo port clean cdo", "sudo port selfupdate" and "sudo port upgrade outdated", respectively but it still gives the same error.
