Neither problem listed below should occur in versions >= 0.18
"_open_mode_string" is not exported by the IO::Handle module at
/usr/local/lib/fvwmconf/lib/IO/File.pm line 108
Something like this means probably an incompatibility. Try removing
/usr/local/lib/fvwmconf/lib/IO/File.pm or whatever its called on your system. perl should
find the file 'File.pm' distributed with your system. This problem arose after
an attempt to fix the problem below.
Can't locate IO/File.pm in @INC
This happened so much that I just put IO::File.pm in the FvwmConf distribution, so this should not
be a problem anymore.
A few perl distributions are missing the file 'File.pm'. It is supposed to be part of the standard
distribution. You can find it
here .
