Installing some packages

Question

Hi guys i'm a new user, i've installed some packages dowloaded from sunfreeware and sun.com with the command pkgadd -d "name" .
more packages such as gcc make and some library but when i'm send the command "gcc".."make" etc... from terminal it sends "command not found".
i've search this problem in some forum and maybe i've find a solution, "a symbolic link".
example "ln -s /opt/sfw/bin/gcc /usr/ucb/gcc"
with this method the gcc command work.
my question is, every time that i make an installation with pkgadd -d i must search the executable file in /opt/sfw/bin/ and after create a symbolic link in /usr/ucb/?
there is an easy way?

You can use ".profile" file, to have PATH env variable. Create ".profile" file, in the home directory of the user (if it doesn't exist).
syntax: export PATH=/usr/bin:/usr/sbin:/opt/sfw/bin:/usr/local/bin/:<other_paths>
therefore every time that i'm installing a new software i must add its path in $PATH variable?Yes
how can i recognize the executable file that have i to insert?Most of the executables reside under "bin" directory, under the installation directory. When you install new software, usually the installers print verbose output on console about the status of the installation. From that verbose output, note down the absolute path to the "bin" directory, and add it to the PATH variable in ~/.profile file.
