compile error: kpsexpand not found

[Edward Sanford Sutton, III]

  When building lilypond from CVS, I run ./autogen.sh 
--with-kpathsea-include=/usr/share/texmf/include/ --with-kpathsea-lib=/usr/
share/texmf/lib/ as one of the steps. Configure and make proceed just fine. 
As my normal user, my path also includes /usr/share/texmf/bin/ in it which 
avoids configure stating 'WARNING: Please consider installing optional 
programs:  kpsewhich' and make failing because it cannot find kpsexpand.
  Once I run make install as root, kpsexpand isnt found (root has a path of /
usr/local/sbin:/usr/local/bin:/sbin:/usr/sbin:/bin:/usr/bin). Is adding 
kpsexpand to root's path the preferred way to properly resolve this build 
error? The end of make install's output is included below to help point out 
the section of the install phase (would more of the output be helpful?) I 
can't recall always having this issue until some of the last few CVS 
versions.
Thanks again,
Ed Sutton
