In Yosemite, Apple removed support for environment variables in launchd.conf, so you need to find another way to set global, system-wide environment variables. For example, if you want solidangle_LICENSE to be automatically set, you could use a launchd plist.

Here’s an example plist that uses launchctl to set the solidangle_LICENSE environment variable.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
 <dict>
        <key>Label</key>
        <string>com.solidangle.setenv</string>
        <key>ProgramArguments</key>
        <array>
        <string>/bin/launchctl</string>
        <string>setenv</string>
        <string>solidangle_LICENSE</string>
        <string>5053@replace-me</string>
        </array>
        <key>RunAtLoad</key>
        <true/>
        <key>ServiceIPC</key>
        <false/>
 </dict>
 </plist>

You’ll need to edit this plist and save it in /Library/LaunchDaemons. The file permissions and ownership should look like this:

-rw-r--r--@ 1 root wheel 661 Oct 22 13:52 com.solidangle.setenv.plist

Use sudo chmod to set the permissions, and sudo chown root:wheel to set the ownerships.
Then load the plist:
sudo launchctl load -w /Library/LaunchDaemons/com.solidangle.setenv.plist

And then restart your machine.
