Hello Carlos,

thanks for your hint! Having in mind, that I could install Dancer 1.3060 
on my Windows system and now knowing, that it installs on Debian 
"unstable", I did some further investigations.

"t/08_session/05_yaml.t" for Dancer 1.3060 introduced some further tests 
using temporary files and directories. Thus, my hope was to find the 
solution for my problem in some platform specific code, that deals with 
these files and directories.

Finally I found out that I "just" had to upgrade my "File::Temp" from 
0.18 to 0.22 - after that, Dancer installations finished successfully!

Concerning the two versions of "File::Temp" there occured some changes 
on output strings ("is not a directory" vs. "does not exist") - Dancer 
installation expected the newer ones. I listed the differences for 
illustration purpose down below ;-)

     ${$options{ErrStr}} = "Parent directory ($parent) is not writable\n";
       ${$options{ErrStr}} = "Parent directory ($parent) is not safe 
       ${$options{ErrStr}} = "Parent directory ($parent) is not safe 
but shorter. Parent directory specifications are stripped from the

       ${$options{ErrStr}} = "Parent directory ($parent) is not safe
