Hi, I cannot reproduce the problem. I tried several ways of installing io from svn. All of them work. I see no pre_install.m function. As I see it, the problem is the following. The compilation and PKG_ADD are called from a machine dependent folder. The path to the installed folder (usually a folder above in the tree, unless you have used the -prefix option) is not loaded yet. Before the call to chk_spreadsheet_support you could addpath and then remove it (though maybe it doesn't collide with anything if you leave ii there). You can get some ideas from the ADD_PKG in main/geometry, which is meant to solve a similar problem. -- M. Sc.
