This may not be the correct place to ask this question, though it
seems potentially relevant to Darwin as well as Mac OS X.
If there's a better place to ask please point me in the right direction.
I read something in an XCode note about Leopard having the ability to
allow you to install XCode in an arbitrary directory...
How does this affect -isysroot? Is there an environment variable set
that one can query to determine the location of the dev tools?
Most "./configure" based projects that support building universal
binaries are likely using the instructions posted at:
http://developer.apple.com/technotes/tn2005/tn2137.html
to set up their autoconf scripts for building universal. That
technote recommends setting -isysroot to /Developer/SDKs/
MacOSX10.4u.sdk, which obviously may be located in a different
location on Leopard.
I'm just wondering if there's a better way to deal with this on Leopard.
Thanks!

P.S. Please don't flog me for posting an XCode question on the Darwin
list... I think this is information that many people maintaining
software ports would like to know. ;)
