sqlite error: disk I/O error

[Ryan Schmidt]

I pressed Control-C while MacPorts was activating a port. Now anything I do with port gives me:


sqlite error: disk I/O error (10) while executing query: ATTACH DATABASE '/opt/local/var/macports/registry/registry.db' AS registry
   while executing
"registry::open $db_path"
   (procedure "mportinit" line 536)
   invoked from within
"mportinit ui_options global_options global_variations"
Error: /opt/local/bin/port: Failed to initialize MacPorts, sqlite error: disk I/O error (10) while executing query: ATTACH DATABASE '/opt/local/var/macports/registry/registry.db' AS registry


How do I recover?
