I have tried installing this package without success on a source build
of sage 4.6 - (I can forward the full build log to the maintainer if
required - and it seems maybe some opengl libraries or some linkage
might be missing - the only package to fail is vtk itsellf  - relevant
extract of log below).


The experimental vtk_meta package is hopeless out of date!
Have a look at: http://sage.math.washington.edu/home/jsp/SPKGS/ETS/

I didn't put much effort in maintaining lately, so you may be on your own.
But I'm happy to answer questions.

Cheers,

I can try and correct this but I am reluctant to try again as every
time I attempt this lengthy build the sage system is hosed in that any
attempt to use the notebook seems to indicate that the symbol
__iteract__ has gone missing! I am obliged to reinstall (or rollback
the entire sage tree) in order to get a working system again.

Anyone with similar experiences, hints or tips to getting this
installed cleanly would be much appreciated.

sage: An error occurred while installing vtk-5.0.3-1
Please email sage-devel http://groups.google.com/group/sage-devel
explaining the problem and send the relevant part of
of /usr/local/sage/install.log.  Describe your computer, operating
system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/usr/local/sage/spkg/build/vtk-5.0.3-1 and type 'make check' or
whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
(cd '/usr/local/sage/spkg/build/vtk-5.0.3-1'&&  '/usr/local/sage/sage'
-sh)
When you are done debugging, you can type "exit" to leave the
subshell.
