'port install/upgrade php5-curl' not working

[phpcurlnotworking@…]

Mac OS X Server 10.6.6 (Snow Leopard)

Was doing a normal 'port selfupdate' and 'port upgrade outdated' when php5-curl failed to update to @5.3.6. Tried a number of things including 'port clean php5-curl' and 'port uninstall php5-curl'.

Here's the relevant output:

---> Configuring php5-curl Error: Target org.macports.configure returned: configure failure: shell command failed (see log for details)

Log for php5-curl is at: /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_php_php5-curl/main.log

Error: Status 1 encountered during processing.
