>Description:
the package lang/rust build fails with this error:

error: bad LLVM version: 3.9.0, need >=3.7

yet, I have LLVM 3.9.0 installed on my system.

How can I deal with that ? I tried to build LLVM again but with same error in rust build time.

here the complete log:

==========================================================================
The following variables will affect the build process of this package,
rust-1.11.0nb1.  Their current value is shown below:

        * PYTHON_VERSION_DEFAULT = 27

Based on these variables, the following variables have been set:

        * PYPACKAGE = python27

You may want to abort the process now with CTRL-C and change their value
before continuing.  Be sure to run `/usr/bin/make clean' after
the changes.
