I was over to their lab one time (near Albany) and it's an amazing  
compilation and build validation system if you have the time to  
invest learning it.

Suggestion:  steal from the experts.

ATRPMS has vtk pre-built:

   http://dl.atrpms.net/sl5-x86_64/atrpms/stable/

so use it unless you need to compile it differently.  If you do,  
steal their SRPM and tweak the build options there, as they've worked  
out the rest already.

Fedora has octave, and here's a link to building octave from Fedora 6  
RPM's on CentOS 5, so it ought to work on SL5:

It seems (naively, perhaps) likely that *SCIENTIFIC* Linux would be  
interested in things like octave/vtk, though it does appear slightly  
more aimed at sysadmins at scientific institutions than scientists.  
Still, one supports the other.  [aside: I don't see immediately why  
they would rather be a distro than a repo with a custom spin script,  
though there must be an answer.  Their wiki doesn't cover their  
current release well, so it's hard to guess, but that sort of re- 
enforces the point.]  Anyway, the point I was getting to is that if  
you do get octaviz/octave building well via RPM, there's probably a  
repo who would take it off your hands.  Axel's would be a place to  
start since he has vtk already, but there's also EPEL which is  
appropriate, and many others like RPM[forge,fusion] who take packages  
willingly.

probably something like

  ccmake . > ccmake-output 2>&1
