Excellent. I'm all for more cooperation between CoCoaLib and Linbox,
since both will be standard components in SAGE.

The last two times I tried the svn version was broken. The version
included in SAGE was the result of Clement Pernet being at SAGE Days 3 and
spending several days fixing bugs and build issues. As soon as linbox
development
moved forward past then, it became broken in various way fairly
quickly. I reported
all the issues I had, so maybe they are fixed now.

Running make check will not be the *default* for builds, but I have been
planning to introduce some form of this for a while. However, I intend
to have optional scripts spkg-check in each sage package, that would
be run after spkg-install succeeds and before the temp build directory
is deleted. Then if one builds using
"make buildcheck"
SAGE would build each package and run spkg-check. If one builds
with just plan "make" then none of the spkg-check's get run.

Excellent!

Best would be for you to send me an spkg-check script for each.
