If you have a compiler (gcc) installed, you can do :
cd /netpbm-10.35.76/
./configure
make
make package pkgdir=$HOME/netpbm
./installnetpbm
...... And please read netpbm-10.35.76/doc/INSTALL.
No compiler ? Then tell, which Linux <name>, <version>, is used.
( Which should be told, every time, you ask a question, please.)
The command 'cat /etc/release' will most often display name/version.
