Thanks for the clarification, Heinrich. It was not apparent to me just
what the Platform package
represented. I'll continue to evaluate Haskell.

I'd guess otherwise, because "" in a #include (having peeked back at the
original message) means it's a locally defined file, not a system header.
That said, it doesn't rule out configure not having created it because it
couldn't find some system header --- but the Command Line Tools should be
sufficient for that.

Signals.h provides an interface to OS process signals, and should be
provided by either the compiler
package, or by the operating system itself. A quick google for "Mac OS/X
Signals.h" tells me that this
header file is, indeed, provided by the X-Code compiler package.

Long ago (2007?) I switched from Linux to Mac because I could not figure
out how to do music on Linux -- in particular I remember audio interfaces
were particularly difficult to configure -- and on the Mac everything "just
worked". As my toolset diverges from the standard Mac audio rigs, though,
that it "just works" seems to become less and less true.
I've got XCode and the command line tools installed already. Installing
those certainly solved some problems, but alas not all of them.
