Unable to uninstall expat @2.0.1_1+universal

[essandess (Steve Smith)]

After upgrading to OS X Lion and running "sudo port -d selfupdate" and "sudo port -p upgrade outdated", I'm getting an error upgrading expat that prevents upgrades of several other packages:

$ sudo port -d upgrade -f expat

Sounds like there is something wrong with the port registry. I don't know what to do about that.

[essandess (Steve Smith)]

Debugging by Google ​strongly suggests that this error message is generated by a call to sqlite in the file ​./base/src/registry/entry.c:

            r = sqlite3_step(stmt);
            switch (r) {
                case SQLITE_ROW:
                    text = (const char*)sqlite3_column_text(stmt, 0);
                    if (text) {
                        *value = strdup(text);
                        result = 1;
                    } else {
                        reg_sqlite_error(reg->db, errPtr, query);
                    }
                    break;
                case SQLITE_DONE:
                    errPtr->code = REG_INVALID;
                    errPtr->description = "an invalid entry was passed";
                    errPtr->free = NULL;
                    break;
                case SQLITE_BUSY:
                    continue;
                default:
                    reg_sqlite_error(reg->db, errPtr, query);
                    break;
            }

Perhaps a simple rebuild of whatever macports binary uses the entry.c code will work? Anyone know how to do this without starting over from scratch?

Did you ever find a solution for this issue? I have a similar one here: ​https://trac.macports.org/ticket/34482

Duping to #34482 since there's some analysis there.
