Installed JAL on the first of my Linux computers just now. It was no problem at all. Just retrieved the new libraries from jsoftware and it was working without any other changes or additional downloads.

Installed JAL on a new computer. I did basically the same as yesterday and it still did not work. At the end what was missing was to remove the NB. from the line in configure unzip ... NB. some text ... after the unzip in the config. After that it started to work. I probably did remove that yesterday also without thinking about it. 2007/3/16, Oleg Kobchenko <[EMAIL PROTECTED]>: > > Thank you for reporting your experience with > installing JAL.
