You can also do a search of one of those libraries here
, put a check next to RHEL 4 and Other.
You'll find there is no RHEL 4 package with those libraries, but there are some noarch. packages that provide all those missing libraries. These packages are listed below. They also have a long list of dependencies listed on the next web page you will find when you click on one of these package links.
You may want to try installing one, if rpm complains about too many missing dependencies, you can back down if you want.
You can also try finding archived (older) versions of Adobe flash at their web site if that's what it takes for that distribution.
