Below is the screen capture : not sure if it is my environement issue , it could be a problem in my configuration. I try to install PDL, and it is failing because of it.

t/08taint.t .............. 1/10 make[1]: chmod: Command not found (#1)
(A) You've accidentally run your script through csh or another shell
instead of Perl. Check the #! line, or manually feed your script
into Perl yourself. The #! line at the top of your file could look like

  #!/usr/bin/perl -w

BEGIN failed--compilation aborted at ./t/08taint_1.p line 6 (#2)
(F) An untrapped exception was raised while executing a BEGIN
subroutine. Compilation stops immediately and the interpreter is
exited.

Compilation failed in require at t/08taint.t line 33 (#3)
(F) Perl could not compile a file specified in a require statement.
Perl uses this generic message when none of the errors that it
encountered were severe enough to halt compilation immediately.

Uncaught exception from user code:
make[1]: Entering directory '/root/.local/share/.cpan/build/Inline-C-0.76-1/_Inline_08taint.14737/build/_08taint_1_p_0965'
make[1]: chmod: Command not found
Makefile:387: recipe for target 'blib/lib/.exists' failed

A problem was encountered while attempting to compile and install your Inline
C code. The command that failed was:
  "make > out.make 2>&1" with error code 2

The build directory was:
/root/.local/share/.cpan/build/Inline-C-0.76-1/_Inline_08taint.14737/build/_08taint_1_p_0965

To debug the problem, cd to the build directory, and inspect the output files.

Environment MAKELEVEL = '1'

Looks like your test exited with 2 just after 1.
