net-snmp fails to build if parallel builds are enabled

[macport@…]

Running on OSX 10.5.8 on Powermac G5 dual 2.5, the net-snmp build fails in the "helper" directory due to out-of-order completion dependency problems. Setting macports.conf to run in single file allowed the build to complete successfully.
