I think it will be rare enough that MacPorts needs to accomodate this
scenario. Rare enough it would not be worth a change to the MP base to
add multiple compile stages.
If this is common with ncurses, why would ncurses simply not go
forward with a flag of --with-wide-and-narrow or whatever.
Perhaps that is where the bug report needs to be focused? Is there any
reason that would be objectionable?
How does this even work? If I build software x with foo support and
then build it again with widefoo support, the foo version will be
overwritten and I end up with just foowide. Or, I otherwise end up
with the last options of which I installed. Installing by hand has
always meant a new install, not an appending ofan existing install,
sans config files perhaps. Aside from making a second installation
I suppose a config file to enable wide character support would be
I'm curious why this is this way from an ncurses perspective? I seem
to recall that ncurses is one that takes a long while to install no
