You don't have permission to write to the destination directory.

make install is usually done as root, unless you're installing to a local 
directory.  Check the ownership and rights to the indicated directory.

You got one:  No input file provided.

Try launching with a valid command line and see how it works.  It 
*shouldn't* segfault (BTW, that is passed by the OS, not by the program, 
so there's not a lot the POV-Ray team can do to change that message since 
it's generated by the OS).

You can get more info about the cause of the segfault and file a bug by 
running it under gdb.
