There is no variant called "noatlas":
$ port variants qrupdate
qrupdate has the variants:
atlas: build with atlas instead of Accelerate framework
g95: build with g95
* conflicts with gcc45 gcc46 gcc47 universal
[+]gcc45: build with gcc45 fortran
* conflicts with g95 gcc46 gcc47 universal
gcc46: build with gcc46 fortran
* conflicts with g95 gcc45 gcc47
gcc47: build with gcc47 fortran
* conflicts with g95 gcc45 gcc46
no_atlas: Legacy compatibility variant
universal: Build for multiple architectures
There is a variant called "no_atlas" which you can use for now:
sudo port install qrupdate +no_atlas
But variants named with "no_" prefixes are deprecated. Instead, disable the positively-named variant:
sudo port install qrupdate -atlas
