You need to use the full layer, rather than trying to copy over
individual components. scikit-learn is a complex recipe to build and
requires a lot of moving parts, without full understanding of the OE
system you should take the layer verbatim. Both errors will be addressed
by using the full layer as it depends on meta-python which is part of
meta-openembedded, and it also bbappends lapack in order to prefer openbl=
as.

Jack.
