Docker for Mac issue in buildEnv-dockercompose.sh

[dogriverrat]

While, yes, the OS requirements do say "Ubuntu" is the OS requirement ... :) ... this can work on OS X under "Docker for Mac". Simple change to buildEnv-dockercompose.sh needed. Change this:

sed -i -e "s/vmhostname/${hostname}/" -e "s/vmipaddress/${ipaddress}/" -e "s/proxyhost/${proxyhost}/" -e "s/proxyport/${proxyport}/" docker-compose.yml

to this:

sed -i "" -e "s/vmhostname/${hostname}/" -e "s/vmipaddress/${ipaddress}/" -e "s/proxyhost/${proxyhost}/" -e "s/proxyport/${proxyport}/" docker-compose.yml

Notice the double quotes after the -i switch. There is a minor difference between the Linux sed and the BSD sed commands. OS X is BSD based so the -i switch requires an argument even if it's empty.
