cpan2rpm cant stat /tmp folder

Im trying to build perl-Heap-Priority for RHEL6. Weired thing is when I run cpan2rpm Heap::Priority it shows following

...
Tarball extraction: [/root/rpm/SOURCES/Heap-Priority-0.01.tar.gz]
Can't stat /tmp/CldQkErG6r/18:51: No such file or directory
 at /usr/bin/cpan2rpm line 392
get_meta(): No such file or directory at /usr/bin/cpan2rpm line 396.
...

Practically this temporary folder is not created. Buy why? my tmp folder permission is 777

drwxrwxrwt.   3 root root  4096 May 29 16:35 tmp

Solution

Known problem, see https://rt.cpan.org/Ticket/Display.html?id=72421. The problem is the space in the user column of the output.

$ tar -tzvf $HOME/rpmbuild/SOURCES/Heap-Priority-0.01.tar.gz |head -1
drwxr-xr-x James Freeman/544 0 2002-05-07 14:51 Heap-Priority-0.01/

Apply the following patch to fix the problem for this module. To get the name, instead of accessing the fifth column, we're accessing the last one. I do not know what else this patch might break, but it should be less wrong than the original code on average.

You could have found out all of this by yourself by using the debugger. Learn to use this tool, it is invaluable.
