Thanks for your quick response. MinGw is already installed on host. It gets automatically installed once we open the CPAN for the first time in command prompt. But I installed it again and it got failed on last step:

I tried again with "perl Makefile.PL machine=none" and got below response now:

  ### GP/PARI library version 2.1.* has many problems fixed in version
+s 2.3.*.

  ### Especially important are the problems with symbols `hiremainder'
+ and
  ### `overflow' - if your build fails and error messages contain thes
+e
  ### words, updating to 2.3.* might allow your use of fast processor-
+specific
  ### assembler code.)

  ### Switching to 2.3.* should be as simple as giving Makefile.PL an 
+option
  ###           version23_ok=1
  ###   (if you or Makefile.PL already downloaded-and-extracted versio
+n-2.1.*
  ###    distribution, give an extra option, force_download).
  ### Alternatively, give option
  ###           paridir=DIRECTORY-of-extracted-distribution

  ### However, keep in mind: v.2.3.* supports only plotting to PostScr
+ipt.

We can observe the errors in last two lines:

dmake.exe: Error code 129, while making 'highlvl.o'
dmake.exe: Error code 255, while making 'libPARI\libPARI.a'
The above steps are given in INSTALL document inside Math_Pari module.
Any idea how to overcome this?
Thanks,
Nikhil.
