Re: [Axiom-developer] yet another problem with dependencies

[Martin Rubey]

Dear Waldek, Gaby,

somewhat unfortunately, I cannot reproduce the failure anymore. Possibly the
administrators changed something, I don't know. It seems that there is now a
link to libreadline.so.5 from libreadline.so that was not present when the
build failed.

I'm very sorry for troubling you,

Martin
