Installing gdbm, db, perl, bc, openssl

gdbm

(if this gives an error, it might have to be installed as root)

tar xf gdbm-1.10.tar.gz
cd gdbm-1.10
./configure  --prefix=/tools 
make -j 8
make install
cd ..

db

tar xf db-5.3.21.tar.gz
cd db-5.3.21
cd build_unix
../dist/configure  --prefix=/tools 
make -j 8
make install

1. this line is hopefully not needed anymore
2. ln -s /tools/lib/libdb-5.1.so /tools/lib/libdb-4.8.so

cd ..
cd ..

perl

tar xf perl-5.12.3.tar.gz 
cp perl-5.12.3-libc-1.patch perl-5.12.3
cd perl-5.12.3
patch -p1 < perl-5.12.3-libc-1.patch
sh Configure -des -Dprefix=/tools/ -Dstatic_ext='Data/Dumper Fcntl IO' 
make -j 12
make install
cd ..

We are now ready for next step
