[Mark Gillies]

Hi guys I've just downloaded version 1.1beta and I'm trying to compile it but 
when I run make in the

kdevelop-1.1-beta1.0

directory I get this error

/tmp/kdevelop-1.1-beta1.0/doc/en/tutorial
make[4]: Entering directory `/tmp/kdevelop-1.1-beta1.0/doc/en/tutorial'
cd ../../.. && automake --gnu --include-deps doc/en/tutorial/Makefile
cd ../../.. && perl am_edit kdevelop-1.1-beta1.0/doc/en/tutorial/Makefile.in
Can't open perl script "am_edit": No such file or directory

I don't know what am_edit is or where to get it can anyone help
