I run this and i guess perl is not installed properly...
# which perl
no perl in /sbin /usr/sbin /usr/bin /usr/bin/X11
# which perl5
no perl5 in /sbin /usr/sbin /usr/bin /usr/bin/X11
#
What can i do for install perl properly??
If you really have perl in dir /usr/bin/perl/ thats seems wrong for me, perl might be available for you like /usr/bin/perl/perl5.6.2, but you should be in correct group, due to permission.
I myself should reinstall perl.
