Issue with bootstrap build affecting pkgsrc builds

[John Klos <john%ziaspace.com@localhost>]

Hi,

I noticed an issue with devel/ncurses that we've seen before:

g++: error: ../lib/.libs/libncurses++.so: No such file or directory
g++: error: unrecognized command line option '-rpath'

This is on a clean amd64 Ubuntu 16.04.3 system which has had nothing done 
besides the usual apt-get update / upgrade / dist-upgrade / whatever.

However, I had forgotten to install g++, so it was installed after 
bootstrap was built. So, I nuked everything, installed g++, then tried 
devel/ncurses again. It worked!

So what's going on with bootstrap when g++ isn't installed that affects 
building packages later? Perhaps we should test for this when building 
bootstrap?

I seriously doubt that ANY email client will ever duplicate the
functionality of Outlook. Its ability to run foreign code is unparalleled.
Even if someone can duplicate that, building a security system into Unix
to allow the email client to have unfettered access to all of the system's
resources is a daunting task in itself, and could take years to duplicate.
