git-1.4.0 make problems

I downloaded the git-1.4.0.tar.bz2 recently and encountered a few problems.

1) The untar process creates a stray file "pax_global_header".
I am using GNU tar v1.13.22 and I get this message :

======================================================================

tar jxf ~/u/source/git-1.4.0.tar.bz2

tar: pax_global_header: Unknown file type 'g', extracted as normal file
======================================================================

2) The make install process ignores the "prefix=..." argument. I have
to comment out one line for this :

======================================================================

diff Makefile git-1.4.0/

94c94 
< #prefix = $(HOME)
---

prefix = $(HOME)

======================================================================

3) The make has a problem with "expat" include and libararies.
I have to add more lines to the Makefile to handle this like some
of the other include and libraries :

======================================================================
351,358c351
< endif
<
< ifndef NO_EXPAT
<       ifdef EXPATDIR
<               # This is still problematic -- gcc does not always want -R.
<               ALL_CFLAGS += -I$(EXPATDIR)/include
<               EXPAT_LIBEXPAT = -L$(EXPATDIR)/lib -R$(EXPATDIR)/lib -lexpat
<           else
---

      ifndef NO_EXPAT

360c353
<           endif
---

      endif

======================================================================

Other than that, it installed okay. I will have to read the docs and
use it to see how it goes otherwise.
