[Gsll-devel] Proposed modification of libgsl locations on linux' (RedHat in particular)

[Liam Healy]

Mirko,

This looks wrong: /usr/local/lib64/lib.  Are you sure you don't
mean /usr/local/lib64?  When I google for that string (with lib64/lib)
literally nothing show that path except your email on mail-archive.
