You have to either put the "PLTCOLLECTS=" at the beginning of the same command that invokes "racket", or you have to use "export". The following two examples should work (note the backslash at the end of one of the lines, for the command that spans multiple lines). #! /bin/sh PLTCOLLECTS="/home/don/.plt-scheme/4.2.1/collects:" \ /home/don/bin/racket -t /home/don/.plt-scheme/4.2.1/collects/DG/hello-world.ss #! /bin/sh export PLTCOLLECTS="/home/don/.plt-scheme/4.2.1/collects:" /home/don/bin/racket -t /home/don/.plt-scheme/4.2.1/collects/DG/hello-world.ss BTW, if your project will be open source software, I suggest using PLaneT development links instead of "PLTCOLLECTS". PLaneT development links have their own difficulties, but McFly Tools makes it easier. <a class="moz-txt-link-freetext" href="http://www.neilvandyke.org/mcfly-tools/">http://www.neilvandyke.org/mcfly-tools/</a> Neil </body> </html>
