When I try to compile mongorestore with ssl support on OSX 10.11.1 I get the following error:

```
~/Documents/projects/mongo-tools$ go build -o bin/mongorestore -tags "ssl" mongorestore/main/mongorestore.go

1. github.com/spacemonkeygo/openssl
   vendor/src/github.com/spacemonkeygo/openssl/bio.go:21:10: fatal error: 'openssl/bio.h' file not found
   #include <openssl/bio.h>
   ^
   1 error generated.
   ```

I assume this is related to the issue that Apple removed shipping openssl with 10.11

```
$ ls /usr/include/openssl
ls: /usr/include/openssl: No such file or directory
```

I installed openssl with brew and also force-linked it
```
brew unlink openssl && brew link openssl --force
```

But that still produces me the error with the missing openssl header include.
