Hello all!

I am trying to compile Amber 18 (and AmberTools 19) on a Cray system. I am
encountering the following issues:

1. While trying to download and install miniconda, the following error

Downloading Python 2.7 Miniconda

Detected Linux kernel. Downloading the Linux installer

Downloading the latest Miniconda distribution

    Detected 64-bit Linux

Resolving repo.continuum.io...,,

Connecting to repo.continuum.io||:443... connected.

To connect to repo.continuum.io insecurely, use `--no-check-certificate'.

Unable to establish SSL connection.

Problem installing Miniconda... see error above.

Configure failed due to the errors above!
2. Then I try to skip python installation using "./configure --skip-python
cray" and then the following error occurs:

Obtaining the cray compiler suite versions, e.g.:
     cc -V
Error: cc is not well formed or produces unusual version details!
       Check for a CC environment variable.
Configure failed due to the errors above!

Running "cc -V" in command line says "gcc: error: unrecognized command line
option '-V'", whereas "cc --version" returns:
/opt/cray/xt-asyncpe/5.27/bin/cc: INFO: Compiling for compute nodes running
gcc (GCC) 4.9.0 20140422 (Cray Inc.)

Do I need to make any special changes in the configure scripts to help it
in detection of compiler version? Please suggest. Thanks.
