You only want to install the tools from the upstream open-iscsi.org 
package. The kernel modules that come with it are newer than the ones in 
your kernel so they have different functions/symbols.

For the iscsi tools, you might just want to use the debian ones that 
came with your distro or use the ofed ones.

If you want to use the open-iscsi.org ones then after you have build them do

make install_user

to just install the tools.

I think you will also want to reinstall your kernel and/or ofed to 
overwrite the open-iscsi kernel modules.
