What Linux are you using?
How did you install the package?
If you are using a rpm based package manager then you can query it to confirm you package is installed, e.g.:

$ rpm -q | grep -i gl

I use Ubuntu also, to query what is installed you can do:

$ dpkg-query -i | grep -i opengl

"dpkg-query -i" lists all the installed packages.
"| grep -i opengl" will cause only those packages that mention opengl (upper or lower case) to be displayed on the screen.

If you know the exact name of the package you are interested in you can run:

$ dpkg-query -l <pkgname>

e.g.:

$ dpkg-query -l libqt4-opengl
