If that's not it, post the output of "perl -V". It might give us a clue.

It does seem to choose gcc, which is evident from the perl -V output below. Does that mean that the perl install was made using gcc as well? If not How should I change it in the perl Makefile.PL?

perl -V output:

Yup, that's a gcc compiled perl alright. Looks like my guess wasn't right.

I thought `perl Makefile.PL` would catch the "different compiler" issue?

Not in my experience, but perhaps someone added code for that recently. It would be a nice feature.

I tried in Sun Solaris. also I have cc compiler. But, I am able to install Devel::Dprof. I did not get any issues. also we should not check with the error like, bksize_t is not declared. because, some variables would have been declared in many header files. Depends upon the package you are installing, the corresponding header willl be used.

more inputs will help.
