Sure enough. When testing, thought it was pulling the install_dir default.
```bash
(ipyipy)12:03:54 {mathjax_profile} ~/code/ipython$ python -m IPython.external.mathjax --dest --profile=rawnb
/Users/kyle6475/.ipython/profile_rawnb/static/mathjax
(ipyipy)12:04:10 (mathjax_profile) ~/code/ipython$ python -m IPython.external.mathjax --dest
/Users/kyle6475/.ipython/profile_default/static/mathjax
```
Shame on me.

Do you think it's alright if I just make the profile option not default?
