[tex-live] error when trying to run ConTeXt

[Wynfield Henman]

TeXLive Version: 2012  ("--all" updated to August 20th, 2012)
The attempted command which ends in an error is:

   texexec -o pdf 659-water-stations.tex

Thei results in: "PANIC: unprotected error in call to Lua API
                         (zlib library version does not match -
header: 1.2.5, library: 1.2.7)"

However /usr/include/zlib.h  is for version 1.2.7, not the 1.2.5
mentioned in the error message.     Any idea of how to fix this, so I
can run ConTexT?
Thanks for any and all help.
