Hello,
I've just built and installed both GHC 7.0.4 and the HP 2011.3.0.0 on
OS X 10.5,
and did not run into any problems (plain ./configure && make && make
install
worked fine). I tested it a little bit, at least the OpenGL
application 'monadius'
works without any problems.
My System:
Darwin Kernel Version 9.8.0 i386
i686-apple-darwin9-gcc-4.0.1 (GCC) 4.0.1 (Apple Inc. build 5493)
Xcode 3.1.3

Personally, I do not care if there is no dedicated distribution for 10.5
as long as building the platform from source works. Maybe one could
add a note that this is also possible (in addition to using older
versions).
