Failure trying to install next/atlantis

[livenson]

Hi,

when running fab loc:py=27,ref=next bootstrap after a long while it fails with

    ******************************************************
    ** ERROR MESSAGES                                   **

    ** Perhaps you forgot to install some of the   **
    ** prerequisite Python modules?  Please look   **
    ** at our INSTALL file for more details and    **

    There were 1 error(s) found that you need to solve.
    Please see above, solve them, and re-run configure.
    Note that there are also 2 warnings you may want
    to look into.  Aborting the installation.

configure: error: Please fix the above Python problem before continuing.

Solution was to switch to atlantis27next env and install missing dependency: sqlalchemy, jinja2, flask, ... "manually". It feels as if deps are deployed into an fabenv environment instead of atlantis27next. Is it possible?
