hi ! 

i'm using curl with ssl so i use --with-openssl
to have php linked against the right libs

beginning on line 545 of "configure.in" it reads:
  AC_ADD_LIBPATH($OPENSSL_DIR/lib)
  AC_ADD_LIBRARY(ssl)
  AC_ADD_LIBRARY(crypto)
  AC_ADD_INCLUDE($OPENSSL_INC)
----

but in "configure" the libraries are assigned like LIBS=" -llib $LIBS "
which means that crypto is linked before ssl BUT ssl needs crypto !!!

it should read:
  AC_ADD_LIBPATH($OPENSSL_DIR/lib)
  AC_ADD_LIBRARY(crypto)
  AC_ADD_LIBRARY(ssl)
  AC_ADD_INCLUDE($OPENSSL_INC)
----

probably other unices have another linking order so adding
another crypto after ssl may help too

have had no such problems on linux tho
