I'm trying to replicate the answer by Gonzalo Medina here: document class for a restaurant menu
However, I am unable to get the decorative corners. My results:

In attempting to remedy this, I figured I needed to install the webomints package. Since it is not listed on Tex Live Utility, I figured I had to download the .zip and install it manually. To do this, I put the webomints folder into ~Library/texmf/tex/latex. I tried to re-compile, but now it fails with the error message:
! Font U/webo/xl/n/80=WebOMintsGD at 95.99976pt not loadable: Metric (TFM) file
not found.
I looked up what this error message means and found that it suggests I am missing the WebOMintsGD.tfm file. I tried looking up how to fix this and found various problems that did not apply.
Any advice is appreciated as I've already spent a couple hours trying to solve this silly problem.
Possibly relevant error messages:
LaTeX Font Warning: Font shapeT1/cmr/m/sc' in size <24> not available
(Font) size <24.88> substituted on input line 86.`
LaTeX Font Warning: Font shapeT1/cmr/m/n' in size <24> not available (Font) size <24.88> substituted on input line 50.Not sure if it's relevant, but none of the folders within texmf existed until I made them to installwebomints.` I believe I am using pdflatex based on the message from RStudio "Running pdflatex on christmasDayDinnerMenu.tex...failed". However, I still tried steps 4 and 5 anyway, but neither worked. The samples compile successfully though. I am using a Mac. – user2205916 Dec 21 '15 at 21:33getnonfreefontsever. Usegetnonfreefonts-sys. The only exception is if you do not have admin rights and then it is worth asking very seriously whether you really need the font that badly and whether you are prepared to put up with the extra hassle (and remember to go through the extra hassle) involved. – cfr Dec 22 '15 at 01:49getnonfreefontsyou now have a problem (or will have). You should undo its doings to prevent this and usegetnonfreefonts-sysinstead if you still want the font. – cfr Dec 22 '15 at 01:51cmr.] By the way, would you consider changing your user name to something a little less generic?
