openSUSE 11.0 (2.6.25.18-0.2-default)

I am trying to build an rpm for the newest version of iscan to see if it solves a problem I am experiencing. Bug # 459215.

Command I am using for build as per iscan readme file.
rpmbuild -tb iscan_2.14.0-3.tar.gz

I fail two dependencies:
libtools-ltdl-devel and sane-backends-devel.

they are not in the normal repositories, or on the retail DVD. I also searched on Webpin and it did not find them. can anyone tell me where I can get these rpms?

Is this correct group to be asking?

Thanks in advance
