Brew trouble w/ Yosemite (gcc47 and subversion)

Mileage may vary on this one, but after upgrading to Yosemite, I encountered two issues with brew.

The first was with gcc47.  After running, "brew upgrade".  It got stuck on the gcc47 formula, which error'd with:

==> Upgrading gcc47
gcc47: OS X Mavericks or older is required for stable.
Use `brew install devel or --HEAD` for newer.
Error: An unsatisfied requirement failed this build.

I decided it was better to move to gcc48 than to bother trying to get gcc47 working. To do that, just install gcc48 and remove gcc47 with:

➜  ~  brew install gcc48
➜  ~  brew uninstall gcc47
That fixed that.  Then, I ran into an issue with subversion, which relied on serf.  The failed to compile with:
#include <apr_pools .h="">
1 error generated.
scons: *** [context.o] Error 1
scons: building terminated because of errors.
There is an open issue with brew for that one. (https://github.com/Homebrew/homebrew/issues/33422)

But you can get around the issue by installing the command line tools for xcode with:

➜ xcode-select --install

If you run into the same issues, hopefully that fixes you.
