Wei,

root_at_hanuman:~# ldd -r /usr/lib/curl_functions_mysql.so
undefined symbol: curl_easy_setopt (/usr/lib/curl_functions_mysql.so)
undefined symbol: curl_easy_init (/usr/lib/curl_functions_mysql.so)
undefined symbol: curl_easy_perform (/usr/lib/curl_functions_mysql.so)
undefined symbol: curl_easy_cleanup (/usr/lib/curl_functions_mysql.so)
undefined symbol: curl_global_init (/usr/lib/curl_functions_mysql.so)
    libc.so.6 => /lib/libc.so.6 (0x00002ba2c971d000)
    /lib64/ld-linux-x86-64.so.2 (0x0000555555554000)

I am using the correct flags from "curl-config", as in my Makefile
(which autoconf creates)

LIBCURL = -lcurl -lgssapi_krb5
