Although this is a very small patch, theUser2 advised me to be careful when creating full paths. I tested it successfully under CentOS 5 and CentOS 6. I intended to use "make_path" instead of "mkpath" if File::Path 2.06 or later was detected. However, I could not figure out how to write a statement like "use File::Path( make_path)" if File::Path->VERSION is 2.06 or later. Specifically, it appears that "use" statements are executed at compile time in Perl, so they cannot be used within an if block. And I cannot just specify "use File::Path" for all versions of File::Path because "make_path" is not exported by default. EPEL 5: http://perldoc.perl.org/5.8.8/File/Path.html EPEL 6: http://perldoc.perl.org/5.10.1/File/Path.html Latest: http://perldoc.perl.org/File/Path.htmlI recommend a more conditional approach testing the existence of the make_path (and the mkpath) function during runtimed using the "defined" command. See: http://stackoverflow.com/questions/433752/how-can-i-determine-if-a-perl-function-exists-at-runtime Mike[...] I will follow that advice for runtime, but I still need to figure out what to do at compile time. http://perldoc.perl.org/functions/use.html "Because use takes effect at compile time, it doesn't respect the ordinary flow control of the code being compiled. In particular, putting a use inside the false branch of a conditional doesn't prevent it from being processed."
Ah, ok.Simply import (use) the complete File::Path package (use File::Path) and reference the make_path and the mkpath function under its full package+function name (i.e. "File::Path::make_path", e.g.).
