lilypond 2.7.27-1 doesn't install and work

[Enrico Licini]

Hi, I tryed to install lilypond-2.7.27-1.linux.sh but it doesn't work.
Opening the file with vim, I saw that there was an error in line 85: $lilydir 
-xzf should be $lilydir -xjf 

Another problem is in the file lilypond in ~/bin: the line should end with $*

But I am not able to solve the last problem: lilypond fails to generate the 
pdf file...

Is it possible to solve these problems?

Have fun with Lilypond!
