when i run brew doctor i get the following:

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
  /miniconda3/bin/python3.7-config
  /miniconda3/bin/python3.7m-config
  /miniconda3/bin/python3-config
  /miniconda3/bin/ncursesw6-config
  /Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7-config
  /Library/Frameworks/Python.framework/Versions/3.7/bin/python3.7m-config
  /Library/Frameworks/Python.framework/Versions/3.7/bin/python3-config

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected header files:
  /usr/local/include/ffi.h
  /usr/local/include/ffitarget.h

can this cause a problem? how to deal with that?

thnx

Subject: [Meep-discuss] still having problems installing

hi,

i have tried the simple (conda) approach and the source code approach for 
installing meep...i do get some progress but at the end of the day plots are 
not generated even for the simplest of examples...i think i have done something 
wrong during installations or that the installations got mixed up somehow and 
cause an error

i would therefore want to completely remove everything that i have installed 
and start fresh with someone helping me through a step-by-step installation 
(and i really need line-by-line help)

would someone be welling to do that please?

could someone suggest a way to first make sure that i uninstall every last 
component of what i have installed?

i have installed Pyhton 3.7 and miniconda and followed john's instructions for 
the installations on sierra regarding installing several packages from through 
homebrew

i have a mac osx mojave 10.14.3

thnx in advance folks
