This a known issue. There are workarounds already published.

Thanks! Except the last command "setenv" does not work (said not found)
used the following command and worked:
export LD_LIBRARY_PATH=$MATLAB$\toolbox\bioinfo\bioinfo\+bioinfoprivate

A quick google search of the "undefined symbol: gzopen64" yielded a variety of responses, all which seemed to revolve around the presence and configuration of the "zlib" library. It seems that some instances of this library have "gzopen64" defined, and others do not.
There wasn't one concrete solution to getting it to work -- some people recompiled zlib, others made soft links, others found they needed to change the library paths so that it could be found, or had found multiple versions on their system.
