For the past few weeks or so, we cannot rebuild our Discourse forum software.

Each time, we get this Bundler error:

> occurred while installing rbtrace (0.5.1), and Bundler cannot continue.

```plaintext

Building native extensions with: '--with-cflags=-Wno-implicit-function-declaration'
This could take a while...
Successfully installed rbtrace-0.5.1
Parsing documentation for rbtrace-0.5.1
Done installing documentation for rbtrace after 0 seconds

```

But it keeps failing

```plaintext
An error occurred while installing rbtrace (0.5.1), and Bundler cannot continue.

```

Any suggestion?  
Or are we doomed, and need to rebuild Discourse from scratch in an entire new directory structure and change all our admin scripts, etc.
