That's only true for users of big 'distributions' which have lots of people, a large professional team or many contributors, to create and maintain the package tree. >>From a different point of view, the problem is also that the developers, using some developing tools (for example the GNU automake and autoconf), don't really know what they are using, or, since "GNU is not Unix", don't verify that their code is POSIX compliant (and to what level etc.; when I began using Unix by discovering Linux, I remember reading a book explaining that for C programming, when linking, you will add always the Glib library because "there are probably things you will need in it!"...). The amount of dependencies of some packages is simply appaling. (One example is TeXlive, because using some macros involve using an amount not necessarily kwown of "other" macros, for a lot of people it is simpler to "take it all" just in order not to "fail"; and this is when you need only a part of it that you discover that this "all" depends on things that you do not have on your system---a C++ compiler and so on). -- Thierry Laronde http://www.kergis.com/ http://www.sbfa.fr/ Key fingerprint = 0FF7 E906 FBAF FE95 FD89 250D 52B1 AE95 6006 F40C
