You guessed it right.  EmacsFromBzr is failing to pick up those
libraries.  I am seeing following lines in src/config.h.

    ,---- src/config.h
    | /* Define to 1 if using libotf. */
    | /* #undef HAVE_LIBOTF */
    | 
    | /* Define to 1 if using libm17n-flt. */
    | /* #undef HAVE_M17N_FLT */

I did a 
        bzr clean-tree --ignored 

and then ran
        ./autogen.sh
        ./configure

and this is what configure is reporting.

I do have the required m17n and otf libraries - both runtime and dev
variations.  Am I missing any other libraries?

Should I file a bug report?
