[collectd] build.sh 5.1 from git clone - libtoolize problem on centos

[ryanL]

hi. after finding the snmp bugs fixed in the latest commits, i figured
i'd try compiling from the 5.1 branch. i'm able to get build.sh to run
(satisfying deps), but it is erroring here:

root at test-app-1 collectd # ./build.sh
+ autoheader
+ aclocal
configure.in:1816: warning: macro `AM_PATH_LIBGCRYPT' not found in library
+ libtoolize --ltdl --copy --force

libtoolize: putting libltdl files in LT_CONFIG_LTDL_DIR, `libltdl'.
libtoolize: `COPYING.LIB' not found in `/usr/share/libtool/libltdl'

at this point it exits.

my google-fu isn't getting me too far on this one.

thanks for continued help!
