   I think I realize what the 'make' problem is probably about -- it's not the 
original 'make' that is of issue, but rather the problem of modifying one of 
the sources and then expecting 'make' to rebuild just the parts that have 
their corresponding sources modified since the last build.  So it will 
probably be necessary to 'make clean' and remake the full source again.
[I have not tested this theory.]

   But if this box is hosting Apache and Subversion repositories, my guess is 
that it probably won't be being used for compiling very much.
