With gcc you can build & install in /home/myname/opt/gcc and then tar it up and deliver to your colleagues /opt directory and it seems to work. They have been pretty careful about using relative paths everywhere. Note to Self: Don't do that with ruby on Linux. You end up with /home/myname/opt hard coded in the ruby executable, especially in the include path $: Curiously enough it seems to do The Right Thing in the code for DOSISH and CYGWIN platforms... but that will do lots of wrong things in other places for the linux platform. Bottom line. Note to Self: Don't do that. John Carter Phone : (64)(3) 358 6639 Tait Electronics Fax : (64)(3) 359 4632 PO Box 1645 Christchurch Email : john.carter / tait.co.nz New Zealand
