Looking for a -devel version

Greetings,

I am trying to run a program that requires the gtkglarea development pack=
age. I=20
have Suse 9.1 that comes with gtkglarea-1.2.2-889 but not the -devel vers=
ion.=20
Can someone let me know where I can find this version of the development=20
package or let me know if there are some alternatives to deal with this. =
I=20
searched the internet and found other versions but have been told that it=
 is=20
wise to use the same version for the development and library releases.=20

I am very new to Linux so any help would be appreciated.

Ned
