[Pkg-openssl-devel] undeclared SSL_OP_MSIE_SSLV2_RSA_PADDING causes error during build of ruby 1.9.3-p484

[Remi Broemeling]

Package: libssl-dev
Version: 1.0.1e-2+deb7u10

It seems that Debian Stable is now unable to build Ruby 1.9.3-p484, due to
Ruby's use of SSL_OP_MSIE_SSLV2_RSA_PADDING.  This was not always the case
(I know for a fact that I have built this exact version of ruby on Debian
7.5+) -- it seems to have just started to happen lately (i.e. towards the
end of May).  I've tried against hosts using libssl-dev
versions 1.0.1e-2+deb7u9 and 1.0.1e-2+deb7u10, and compilation on both of
those versions fails with the following error during OpenSSL:

compiling ossl_ssl.c

ossl_ssl.c:382:35: warning: variable ‘ret_obj’ set but not used

ossl_ssl.c:1988:5: note: each undeclared identifier is reported only once
for each function it appears in

make[1]: *** [ext/openssl/all] Error 2
make[1]: Leaving directory `/tmp/ruby-1.9.3-p484'
make: *** [build-ext] Error 2

Apparently, ruby has patched the problem in v2.1.1 (as per
http://svn.ruby-lang.org/repos/ruby/tags/v2_1_1/ChangeLog).  That changeset
seems to have been backported into the debian package for ruby (as per
http://patchwork.ozlabs.org/patch/350725/)... but compiling the stock ruby
from source is still unworkable due to this problem.

Is this behavior (being unable to build older ruby from sources) expected?
 Or is this a bug in Debian Wheezy's version of the libssl-dev package that
will be fixed in a forthcoming version of the packages?

Thanks!
