dyld: Library not loaded when using gm module with ExpressJS - express

Question

I'm trying to use the gm module with ExpressJS to resize images on the server. The resize wasn't working as expected so I changed my code to just console.log a value, which I could immediately see was giving me an error. I installed ImageMagick with Homebrew.
CODE:
var gm = require('gm')
...
gm('uploads/4d03e739a7302fc7f68d022339205dee.JPG').filesize(function(err, value){
if (err) {
console.log(err)
} else {
console.log(value)
}
})
FIRST ERROR:
{ [Error: spawn ENOENT] code: 'ENOENT', errno: 'ENOENT', syscall: 'spawn' }
So, I did some Googling and read that I should change
var gm = require('gm')
to
var gm = require('gm').subClass({ imageMagick: true })
Now I'm getting this error, which I can't find anything about:
{ [Error: Command failed: dyld: Library not loaded: /usr/local/lib/liblzma.5.dylib
Referenced from: /usr/local/bin/identify
Reason: image not found
] code: null, signal: 'SIGTRAP' }
I've tried uninstalling ImageMagick, updating Homebrew and reinstalling. I've also tried uninstalling and reinstalling freetype and running brew unlink freetype && brew link freetype in terminal.

Answering my own question...the answer was difficult for me to find so maybe this will help somebody.
Looks like there is a problem with Homebrew's bottled build of ImageMagick.
Uninstalling ImageMagick and reinstalling with the --build-from-source flag did the trick for me.
brew install imagemagick --build-from-source
