Many ports in MacPorts build differently depending on the major  
version of Mac OS X. So after upgrading to a new major version of Mac  
OS X you should rebuild all ports. Only you have to do that in  
dependency order. MacPorts doesn't include an automated way to do  
this. My recommendation is to move /opt/local aside (rename it to / 
opt/local-10.4 for example) and then reinstall the latest MacPorts  
and the ports you need. You may also have data and configuration  
files in /opt/local-10.4 you may need to move over to /opt/local.

That sounds like you partially installed a port (i.e. got through the  
configure phase at least) while you were running Mac OS X 10.4 and  
are now trying to complete that installation with Mac OS X 10.5.  
Removing all of MacPorts as above will coincidentally fix this. Or  
you can try "sudo port clean"ing whatever port it is you're getting  
this error on, so that it will start over and run the configure phase  
again.
