Re: Centos 5 compiling 3.6 problem with BLAS? ATLAS?

Ah hah! That did the trick - thank you for your help.

yum install blas-devel
yum install lapack-devel

I tried the enable-64 option but it fails, which makes sense I guess
after reading

That will be a challenge for another day :) Thanks for getting me up
