I think it might be good idea for CPAN support for Perl, possibly PEAR support for PHP and whatever the Python community use to be integrated into YaST. With YaST identifying the appropriate development RPMs and installing them as required. This would help non-Perl,php,Python people maintain their installations in these languages and could be of benefit for those who choose to work with these languages. AFAIK there is no cpan equivalent for checkinstall, so generating an RPM from a cpan install is unlikely to be straightforward. > The worst thing, for me, is that the "rsnapshot" application does an > examination of itself without discovering any problem, does the backup > claiming sucess, and fails to save anything.

FWIW, that's what I've done for years and generally without any issues at all. Very occasionally an underlying compiled library from the Suse distribution is so old that the current CPAN release can't deal with it, but usually the CPAN modules will cope with binary libraries that are considerably older than themselves. To a large extent, these occasional difficulties are self-inflicted because I run Suse releases way past their sell-by-date.

Many of the SuSE 10.2 Perl module RPMs from packman are badly out of date. The SuSE Perl stuff is a bit better but still lags (as would be expected). Only spotted problem when SuSE servers were down and was checking out what I thought were issues with a Perl Module to find that my current version of the module was 2 major releases out of sync. I think in future I will probably maintain my Perl stuff from CPAN.

In this case, lchown() shall change the ownership of the symbolic link file itself, while chown() changes the ownership of the file or directory to which the symbolic link refers. RETURN VALUE Upon successful completion, lchown() shall return 0. Otherwise, it shall return -1 and set errno to indicate an error. blah blah blah. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
