Warn instead of error out for missing .env file of PORT_GIT_DEPS programs?

[fanbo-meng]

For the programs specified for PORT_GIT_DEPS, e.g make, git, they are already pre-installed somewhere on the machine I'm using, but I have to manually create empty .env files under ${HOME}/zot/prod/${dep}/.env in order for the build.sh script to keep going and not report error during checkDeps() step. This gives a bit inconvenience and confusion.

One other alternative would be to check if the dependency executable can be found in user's PATH (using type) and if it is, do not emit the error

For git in particular, we do need a particular level of git to operate. So if we do this, we should also add a check of the git version to make sure it is 'new' enough.

I did add 'git' and 'xlclang' version checks to the code. @fanbo-meng I am thinking once we get 'git' built from open source this problem will 'solve itself' since it will then have a .env file?

[fanbo-meng]

yeah I guess if we always build PORT_GIT_DEPS programs like git from open source and use it in building the actual program then .env would always be there.

@fanbo-meng ok to close?
