[vdtak@…]

Dear Macports team,

Installing gildas gives the following error message. How can I solve or circumvent this issue?

In the future, please use WikiFormatting and Cc the port maintainers (port info --maintainers py27-numpy), if any.

Solution is in the output you supplied. Match your py27-numpy variants with your installed atlas variants.
