Cannot install boost, lhapdf and pythia8

Never seen this one.

I would actually advise to uninstall gcc8 and only keep gfortran.
This is the setup that I have on my mac (such that you are sure to always use clang everywhere which is a quite stable setup.

Cheers,

Olivier

Apparently is not trivial to uninstall gcc on a mac.
So I tried
$brew unlink gcc
Unlinking /usr/local/Cellar/gcc/8.2.0... 0 symlinks removed

then I hit
mg5_aMC> install pythia8
and I get the same result.
The problem is not solved.

Then I would advise to install (manually) lhapdf6.2
MadGraph is compatible with that version of lhapdf but that version does not require boost.

Cheers,

Olivier

Now I am getting the following message when hitting ./configure on the manual installation

"checking for a BSD-compatible install... /usr/bin/install -c

That sounds ... bad.

Your installation of gcc is probably partially present,

normally you should have the following one:
$ c++ --version
Apple LLVM version 10.0.0 (clang-1000.11.45.5)
Target: x86_64-apple-darwin18.2.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

It looks similar to what I have:

"
Apple LLVM version 10.0.1 (clang-1001.0.46.4)
Target: x86_64-apple-darwin18.5.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin"

is it because i don't have it installed in the Xcode apps?
