I think it needs to add to readme
http://search.cpan.org/~jesse/perl-5.12.1/README.solaris#GCC if it virtualbox then mount win7 directory to unix directory:
mount -F vboxfs -o uid=100,gid=10 solaris /mnt/vbox_share
gunzip perl-5.12.1.tar.gz
tar xf perl-5.12.1.tar
cd perl-5.12.1
to use make add /usr/ccs/bin/ - sure (you write about it)
to use gcc add /usr/sfw/bin/
so befor
PERL_HOME=/rwa/data/team/MISHNIK/develop/perl/perl_5_12/
./Configure -des -Dcc=gcc -Dprefix=$PERL_HOME
we need to add this directories to $PATH:
PATH=/usr/ccs/bin/:/usr/sfw/bin/:$PATH
