 updated load commands do not fit (the program must be relinked, and you
 may need to use -headerpad or -headerpad_max_install_names
 > }}}

 MacPorts puts `-headerpad_max_install_names` into `configure.ldflags`
 automatically specifically so that `install_name_tool` can be used in this
 way, but this build isn't making use of MacPorts `configure.ldflags` (and
 it probably should be).

 I'm not entirely sure where the problem is. I see that the port is
 disabling the build phase and doing its building and installing together
 in the destroot phase, which is weird; ports should usually build in the
 build phase and install in the destroot phase. If fixing that doesn't fix
 the problem, then I would examine the python 1.0 portgroup. It's possible
 this problem affects all python modules. I don't see the string
 `configure.ldflags` anywhere in the python portgroup, which surprises me.
 For comparison, I do see `configure.cflags` and `configure.cxxflags` used
 there.

 This problem may be affecting you especially, and might not be apparent
 when we build it, because you're using a custom MacPorts prefix
 (/Users/Nasy/.macports) that is longer than the default prefix
 (/opt/local).
