Trouble installing boost on Leopard using macports

If your internal domain is .local, you will have a problem resolving names via DNS. There is an old article on Mac OS X Hints which describes a solution:

I created a company.local file in /etc/resolver, and populated this file with the nameservers for the company.local AD domain. This allows Mac OS X to use standard DNS to resolve company.local (or subdomain.company.local), while still allowing Rendezvous to operate as expected.

The only drawback I've seen to this approach is that the nameservers in this company.local file don't update via DHCP, so I have to update them manually.

Here is a more official support document from Apple which will parse your existing /etc/resolv.conf to populate the file in /etc/resolvers.

I had the same issue - the fix was to recompile ruby to be 64-bit instead of 32.

You can check to see what architecture your ruby uses like this:

> file `which ruby`
/usr/local/bin/ruby: Mach-O 64-bit executable x86_64

If it reports i386 instead of x86_64 - then you probably have the same issue.

(before recompiling mine was "Mach-O executable i386")

Kind of a pain because after this you'll need to recompile/reinstall any gems w/ native extensions. I haven't done this yet, but I saw somewhere that you might be able to do it "easily" using sudo gem pristine --all
