Error installing on OS X 10.5

[scott-phillips-sp]

I believe this is an issue with installing the latest version of XCode not creating all the symlinks it use to. bufferutil had a similar issue, websockets/bufferutil#17. I was able to fix the issue following the advice in that PR:

$ cd /usr/local/lib
$ sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.5.dylib
$ sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.4.dylib

Here's the console output of npm install:

npm install utf-8-validate

Was having this issue also. Fixed with:
sudo ln -s /usr/lib/libSystem.B.dylib /usr/local/lib/libgcc_s.10.5.dylib
as recommended.

Updating the "Command Line Tools" should fix this, closing. Please reopen if needed.
