Warnings popped up after first install

[mikenlee]

Thanks for making this available on emacs.

Wanted to notify maintainers initial set of warnings I received after first installing virtualwrapper.el

Warning (bytecomp): assignment to free variable ‘eshell-path-env’
Warning (bytecomp): ‘mapcar’ called for effect; use ‘mapc’ or ‘dolist’ instead
Warning (bytecomp): called-interactively-p called with 0 arguments, but requires 1
Warning (bytecomp): assignment to free variable ‘eshell-modify-global-environment’
Warning (bytecomp): assignment to free variable ‘eshell-path-env’
Warning (bytecomp): the following functions are not known to be defined:
    projectile-project-root, eshell-stringify-list, pcomplete-here*

Is there anything here that indicates a faulty installation?
