lyx we already have - it is in addons repo and if you don't have it
already you can easily add it with
yum install puias-addons
after which you should be able to install lyx. For the other two we
usually stick scientific/computational stuff into computational repo.
gretl is easy enough to rebuild - I've added it to the computational 6
repo - you'll have to add it to your machine with
yum install puias-computational
and then you should be able to do yum install gretl. I'll also take a
stab at qgis but that one has more dependencies and I am not sure all
will compile for rhel6 (gee, it is already getting old...).
