Comment (by mascguy):

 Replying to [comment:19 kencu]:
 > There is a certain elegant beauty to simplicity. Have a look at the
 formula for mpich on Homebrew.

 While many of their formulas are indeed simple, they also limit macOS
 support to 10.14+. That alone makes things far easier. (Though frankly,
 I'm glad we support macOS releases back to 10.6. It's a key
 differentiator, and one that I'm proud to support!)

 However, their formula for `mpich` doesn't look all that simple. Which
 isn't a surprise, as some hoops are required to properly configure and
 build precisely what's desired:

 > Here's the Portfile I'm using on my systems to install mpich-default. It
 installs, with FORTAN support, using MacPorts default compiler, with no
 fuss. (I have installed 10.4, 10.5, 10.6, 10.7, 10.14, and 10.15 so far).

 The existing `mpich-default` should work as-is, if you simply add the
 following to the section entitled "Compilers supported across-the-board:"

 ```
 dict set clist default {}
 ```

 What's the error/issue you're encountering, using our existing port with
 the aforementioned change?
