I did the same thing..
I modified configure.in as:
--SNIP--
AC_MSG_CHECKING(for SSLeay)
ac_cv_ssleay_path=no
incdir=no
for dir in /home/shashank/openssl-0.9.6b /usr /usr/local /usr/local/ssl 
--SNIP--
Then i ran aclocal and autoconf.. However I got the following error with 
autoconf
--SNIP--
configure.in:1: error: possibly undefined macro: dnl
      If this token and others are legitimate, please use 
m4_pattern_allow.
      See the Autoconf documentation.
configure.in:510: error: do not use LIBOBJS directly, use AC_LIBOBJ (see 
section `AC_LIBOBJ vs LIBOBJS'
--SNIP--

BUt I think the conifgure script was still modified to reflect the changes 
that i made as i get the following output.
--SNIP--
checking for SSLeay... /home/shashank/openssl-0.9.6b
checking for des_cbc_encrypt in -lcrypto... yes
checking cast.h usability... no
checking cast.h presence... no
checking for cast.h... no
checking rc5.h usability... no
checking rc5.h presence... no
checking for rc5.h... no
--SNIP--

I checked config.log for rc5.h and i get the following error:
--SNIP--
configure:9082: result: no
configure:9178: checking rc5.h usability
configure:9191: gcc -c -g -O2 -Dss_family=__ss_family -Dss_len=__ss_len  
-I$(srcdir)/missing conftest.c >&5
configure:9261:17: rc5.h: No such file or directory
configure:9194: $? = 1
-SNIP--

I have very preliminary experience with the gnu autoconfiguration tools. 
So if something is wrong, please let me know.

Bottomline: I still can't get tcpdump to compile with crypto code.
Thanks
