/usr/bin/ld: cannot find -latlas

Question

I'm trying to install code which I've successfully installed in the past on a new computer, and am running into problems.

This is on Fedora, using scons. The previous successful installation was on Ubuntu.

When I type scons, it gives the following error:

/usr/bin/ld: cannot find -latlas

I have successfully installed atlas-devel via yum.

If it helps, you'll find below the top level SConstruct File (--- indicates redacted code)

It turns out the issue was that atlas puts the libatlas.so in /usr/lib(64)/atlas/... Thanks to @Dave_Bacher for information on how to deal with this, namely

Add /usr/lib/atlas to the LIBPATH array in your default_env:

LIBPATH = [BUILD_LIB_DIR, /usr/lib/atlas]
