Part of the problem seems to be misleading / incorrect error messages:

>> ### No toolset specified. Please use --toolset option.

seems to be an error message from bjam, but I think "--toolset" should instead be "toolset".  I don't know anything about ./bootstrap.sh though.

I use something like

  bjam toolset=gcc ... lots of other options ...

with a user-config.jam file containing something like

    using gcc :  :  /usr/local/bin/mygcc  :  <cxxflags>="..."  ;

[Remember that whitespace separation matters in user-config.jam]
