Yes...

Just using a pre-configure or post-configure block to run ./configure via system would probably not be best, because when MacPorts runs ./configure, it supplies lots of environment variables, which running it via system would not automatically supply.

A hack I've used before (in the php-1.1.tcl portgroup, for example) is to call portconfigure::configure_main to get MacPorts to run configure again, after changing some options. For example you might do:


configure.args --with-csl

post-configure {
    configure.args-replace --with-csl --with-psl
    portconfigure::configure_main
}


Technically ports are not supposed to use things like portconfigure::configure_main because it's not part of the official exposed MacPorts API, so theoretically it could change in the future and the port would break... but it should work for now.
