[Libguestfs] Error while compiling febootstrap (a prereq for libguestfs)

I want to install libguestfs in Centos 5 Kernel version 2.6.18.8-xen. For this, I have sucessfully installed ocaml-3.12.1, findlib-1.2.7. Now when  I am trying to install febootstrap-3.13 (another prereq for libguestfs), I am getting the following error during 'make'. [root@M febootstrap-3.13]# make make  all-recursive make[1]: Entering directory `/home/pf/febootstrap-3.13' Making all in lib make[2]: Entering directory `/home/pf/febootstrap-3.13/lib' make  all-recursive make[3]: Entering directory `/home/pf/febootstrap-3.13/lib' make[4]: Entering directory `/home/pf/febootstrap-3.13/lib' make[4]: Nothing to be done for `all-am'. make[4]: Leaving directory `/home/pf/febootstrap-3.13/lib' make[3]: Leaving directory `/home/pf/febootstrap-3.13/lib' make[2]: Leaving directory `/home/pf/febootstrap-3.13/lib' Making all in src make[2]: Entering directory `/home/pf/febootstrap-3.13/src' ocamlfind ocamlopt -warn-error CDEFLMPSUVXYZ -package unix,str -c febootstrap_cmdline.ml -o febootstrap_cmdline.cmx File "febootstrap_cmdline.ml", line 1, characters 0-1: Error: Could not find the .cmi file for interface febootstrap_cmdline.mli. make[2]: *** [febootstrap_cmdline.cmx] Error 2 make[2]: Leaving directory `/home/pf/febootstrap-3.13/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/pf/febootstrap-3.13' make: *** [all] Error 2 Does anyone have idea to fix it. --Irfan
