Thank you for your answer.
THe output like that :
root at ubuntu:/opt/xcomm# gdmd
Can't exec "/usr/local/bin/gdc": No such file or directory at 
/usr/local/bin/gdmd line 236.
Use of uninitialized value $gcc_version in scalar chomp at 
/usr/local/bin/gdmd line 237.
Use of uninitialized value $gcc_version in pattern match (m//) at 
/usr/local/bin/gdmd line 238.
Can't exec "/usr/local/bin/gdc": No such file or directory at 
/usr/local/bin/gdmd line 523.
