Meanwhile, whyncha make a tarball? Every linux/unix cud then use the browser in it's latest version

perhaps you might wish to consider alternate package formats such as tarballs if you cannot prepare a REDHAT package.

I want to install Opera on CentOS (Redhat RHEL clone). However your download site (www.opera.com) is offering a .deb package file with no other package format choices. Redhat requires RPM formatted packages. .deb packages are used for Ubuntu and Debian; no good for Fedora nor RHEL OSes.
