linux compat startup permission issue

Trying to run OpenTaxSolver for the first time...

$ ./Run_taxsolve_GUI
Issuing: '"./bin/ots_gui2" &'
sh: cannot redirect standard input from /dev/null: Permission denied
./bin/ots_gui2: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

I'm reluctant to run as root; is there an easy way around this?
