The log says:
:info:configure checking for BABL... no
:info:configure configure: error: Package requirements (babl >= 0.1.10) were not met:
:info:configure
:info:configure Requested 'babl >= 0.1.10' but version of babl is 0.1.2
What version of the babl port is installed? (use "port installed babl" to find out). The version currently available in MacPorts is 0.1.10 since r95346 so if your portfiles are up to date (run "sudo port selfupdate" to update them) then this error should not be happening.
Is there a config.log file within the directory identified by the command "port work babl"? If so please attach it to this ticket as well.
Note that the commands "sudo port clean" and "sudo port install" only accept port names; they disregard any version numbers you supply.
