Looks like Slackware is getting ready for a new release. A really big set of updates came down the pipeline. Nearly everything works perfectly. Two things are causing problems for me. One is mouse, one is Perl.
The mouse issue is happening at home, but not at work, so it's probably something in Xorg related to the video card type. They are different between work and home. If I want to cut some text from an xterm to use elsewhere, or want to grab a bottom corner of a screen and pull on it to expand it, or click in a text box on a website, the mouse position is wrong. If I click where I am used to clicking, wrong things happen. I have to click about one line down and several characters to the right. I can still do the actions, but I have to fudge it to get what I want. Then go to work and do it the old way.
I'm watching the posts at Linux Questions for notes about it, and expect it to be fixed shortly.
The second problem happens at work and at home. When I try to run any of my Perl scripts that use the File::Copy module, or other modules that tap into the List::Util module, I get this error:
/usr/bin/perl: symbol lookup error: /usr/local/lib/perl5/auto/List/Util/Util.so: undefined symbol: Perl_xs_apiversion_bootcheck
Some of my scripts no longer work, but I can get around them. I might have to remove Perl completely, then reinstall it. I remember something similar from a long time ago, the last time Perl had a major release number change. I'll work on that.
If it persists, I will rewrite those scripts to Python and move on.
