Ubuntu has this package, at least the ubuntu 6.1 that I have installed here and no ISPConfig version compiles without it. This is also true for 2.2.7.
How can I do that without loosing all?
1) Dont panic.
2) Dont try to solve it on your own by doing any steps that we dont tell you to do so here.
2) Try to follow the steps that I tell you to solve the problem.
Please post the output of:
