autom4te: need GNU m4 1.4 or later: /usr/local/bin/m4

hi

i had allready "m4" from the repro installed, did an autoconf inside the bridge-utils sources directory, no complains, all went fine till the make process was complaining about
a bug  https://bugzilla.redhat.com/show_bug.cgi?id=895141 "if_bridge.h:184:20: error: field 'ip6' has incomplete type". So though i build the linux-3.15.5_headers_api as extension, removed the old 3.8 api headers and installed the new api headers (3.15.5) !
Then i created a fresh directory for bridge-utils and did an "autoconf" again but then TC complains about "autom4te: need GNU m4 1.4 or later: /usr/local/bin/m4" .... 
i deleted the Extension , did an reboot and installed the "m4" again from the repro, went into the bridge-utils sources directory and did again autoconf, but this time no complaing about "autom4te: need GNU m4 1.4 or later: /usr/local/bin/m4" !!!!!!!!!! 

so my question is:
what went wrong before from "m4" why i needed to delete and reinstalling "m4" from the repro ?

Thanks and Good Night 1.24AM here zzZzzZZzZzZ ;-)
Best regards

You probably forgot to load it.

No, i dont think so cause before, i did an autoconf inside the source directory of bridge-utils and all was fine till i replaced the linux_headers_api.
Also it was before under /mnt/sda1/tce/optional/m4.tcz and also in the onboot.lst.
