Thanks again for your help.
Do both of the examples you site above have to be included when you run the package installer?
I created a bin directory and an include directory in my home directory, and again attempted to install the deblibstdc++6_4.3.2-1.1_i386.deb
I tried these commands:
[argonauts]$ export PATH=$loc/bin:$PATH
[argonauts]$ export CPATH=$loc/include:/usr/local/include:$CPATH
[argonauts]$ dpkg -i deblibstdc++6_4.3.2-1.1_i386.deb
And I got this response:
dpkg: requested operation requires superuser privilege
...then I tried prefixing the command with "sudo" and got the "not a super user, this incident will be reported" message again.
Can you give me any other tips? As a reminder, I'm a Linux newbie, so I don't always know which text in your examples is a placeholder which I should replace with my own directory or file names, and which text can be typed literally.
