scusa, puoi mettere il link del tutorial a cui ti riferisci?
Poi ti volevo segnalare questo link
http://wiki.freepascal.org/Installing_Lazarus (http://wiki.freepascal.org/Installing_Lazarus)
quì trovi un semplice script che installa in /opt (puoi provare sostituendo 686 con arm)
#!/bin/sh
#installing required packages
sudo apt-get install build-essential
sudo apt-get install libgtk2.0-dev
sudo apt-get install libgdk-pixbuf-dev
#installing Free Pascal source
cd /opt
sudo wget http://nchc.dl.sourceforge.net/lazarus/fpc-src-2.4.2.source.tgz
sudo tar -xvf fpc-src-2.4.2.source.tgz
sudo mv fpc fpcsrc
#installing Free Pascal
sudo mkdir fpc
cd fpc
sudo wget http://nchc.dl.sourceforge.net/lazarus/fpc-2.4.2.i686-linux.tar
sudo tar -xvf fpc-2.4.2.i686-linux.tar
echo "Enter '/opt/fpc' when prompted 'Install prefix'"
sudo sh install.sh
#adding fpc path to the PATH
echo "#FPC PATH" >> ~/.bash_profile
echo "if [ -d /opt/fpc/bin ] ; then" >> ~/.bash_profile
echo PATH=/opt/fpc/bin:"${PATH}" >> ~/.bash_profile
echo "fi" >> ~/.bash_profile
#installing Lazarus
cd ../
sudo wget http://nchc.dl.sourceforge.net/lazarus/lazarus-0.9.30-0.tar.gz
sudo tar -zxvf lazarus-0.9.30-0.tar.gz
PATH=/opt/fpc/bin:"${PATH}"
sudo chmod -R 777 lazarus
cd lazarus
make clean all
./lazarus
