xinitrc

[tmaurizio at alice.it]

hallo to all,
I have a little problem with xinitrc:
my mac port installation, work fine. I wish work with anothe  
WM ...What I must configure for run windowmaker?
I tried to configure xinitrc in /usr/x11/lib/x11/xinit/xinitrc  and  
also xinitrc.d  then Itried to add 'source ~/.profile' to the  
file .xinitrc but
this also don' t produce some result.
I would wish some clarification for these files...there is something  
that I don't understand...:))
tanks & regards
maurizio

macport version 1.700
x11 2.3.1
