Installing on AIX fails

Hi all,

I was trying to install git in a development and testing server we
have. The first problem was that AIX 'make' tool does NOT support
conditionals in makefiles, and display errors such...


[...]
"Makefile", line 1003: make: Dependency line needs colon or double
colon operator.
"Makefile", line 1007: make: Dependency line needs colon or double
colon operator.
"Makefile", line 1009: make: Dependency line needs colon or double
colon operator.
"Makefile", line 1011: make: Dependency line needs colon or double
colon operator.
[...]


... until I get stucked. Well, I solved this by just using GNU make,
then I compile:


$ /usr/linux/bin/make prefix=$HOME/apps/ NO_OPENSSL=1 NO_TCLTK=1
NO_EXPAT=1 PYTHON_PATH=/usr/local/bin/python


and it all works, with angels singing and everything... a testing repo
works fine for a test drive without installing, excepting 'git log'
that just don't display anything.
Now, when I feel good to install it...


$ /usr/linux/bin/make prefix=$HOME/apps/ NO_OPENSSL=1 NO_TCLTK=1
NO_EXPAT=1 PYTHON_PATH=/usr/local/bin/python install

[...]
install -d -m 755 '/myhomedir/apps/bin'
getopt: illegal option -- d
Usage: install [-c dira] [-f dirb] [-i] [-m] [-M mode] [-O owner]
               [-G group] [-S] [-n dirc] [-o] [-s] file [dirx ...]
make: *** [install] Error 2



Now the installing process fails because of the AIX 'install' tool and
I wonder, can I patch/configure the installing process for AIX? May be
a set of utils for building in such systems would help some people.

PD: If you don't understand me please let me know it and I will try
again : )  My english could be horrible since I'm Argentinian.

PD2: I don't know if AIX python path is always /usr/local/bin/python,
but I've seen that git Makefiles set /usr/local/bin/python for FreeBSD
only:

git_remote_helpers/Makefile:
ifndef PYTHON_PATH
        ifeq ($(uname_S),FreeBSD)
                PYTHON_PATH = /usr/local/bin/python
        else
                PYTHON_PATH = /usr/bin/python
        endif
endif

I think 'test' the file is a good way for auto-configuration.

Cheers,
Dario
