Well, I did do an edit before your reply came in. I added an
"include Makefile.options"
to the Makefile, then 'make' presented the option table. I made an error requiring a conflict edit. Then on a re-make the option table failed to be presented, I had to rem it out, then it ran OK, except for several stalls in some dependencies. Could this be because I was working through a KDE interface?
I've looked again at the port's config page, but I can't still find any reference to the usage of a "Makefile.options" file, there is also a "Makefile.webplugins" in the ports distro.
Any advise on how to use these?
