aclocal only picking up /usr/local/share and not /usr/share

[Maynard Johnson]

Hello,
I have installed a version of aclocal into /usr/local that's newer than my 
distro's version (I needed a fix from the newer version).  But then I ran into 
a problem recently where the build of some package was failing because aclocal 
was not finding the pkgcfg.m4 file in /usr/share/aclocal.  I created a dirlist 
in /usr/local/share/aclocal and added /usr/share/aclocal to it.  That did 
indeed resolve the problem.  But is that the best way to resolve this problem?  
Maybe this is documented somewhere, and I just didn't see it, but it took me 
longer than I care to admit to resolve this.  Seems like it could be a fairly 
common problem.  Have others solved it in a more clever way rather than telling 
system owners they need to create a new dirlist if they've installed aclocal in 
a non-standard location?

Thanks.
