gcc-4.6.2 and M4 dependencies

[benedicte jourdain]

Hi to all,
I'm a newbie to macport and this list running tiger 10.4.11 on ppc G5  
970 FX.
yesterday, i install macport and then an ambitious gcc-4.6.2 from  
scratch. The standard M4 (/usr/bin) version is only 1.4.2 and install  
process need a more recent version.
Could you please add the dependency ?
Is it possible to retrieve the ./configure params (if some) after  
install ?
Many thanks for your work.
Regards
