(hi gene, hope you don't mind, i'm cc'ing the list back again, i
assume you accidentally didn't hit "reply-to-all?" or that i did, if
so, whoops...)

there's a file search "thing" somewhere, for apt... it's a plugin (i
think)... although i suspect you simply have the wrong version of
openssl installed.
ok so i do have /usr/include/openssl/bio.h (makes it easier if
someone else has it....) and so i can find it with:
$ grep bio.h /var/lib/dpkg/info/*.list | grep openssl
and that gives:
/var/lib/dpkg/info/libssl-dev:amd64.list:/usr/include/openssl/bio.h
/var/lib/dpkg/info/nodejs.list:/usr/include/node/openssl/bio.h
shriieeeek wtf am i doiiing with nodejs installed, dieee nodejs,
dieeeee sorry about that, adverse reaction to node.js
ok so you'll need to do "apt-get install libssl-dev" and that *should*
get you the missing openssl/bio.h file.
if you run into any other difficulties with missing packages, try this:
"apt-get build-dep linux-image-4.something.something"
that will install *all* build dependencies for a *debian* kernel build
process... which (warning) may be a little bit more than you bargained
for, you'll have to review what it recommends to install before
proceeding, ok?
basically when doing a build of a package that's similar (or
identical) to an existing debian one, the trick of installing
*debian's* build dependencies for the same name uuusuuually does the
trick of getting you everything you'll need to build that "vanilla"
upstream {whatever}.
problems come when debian sets different options from the default, and
you can always inspect the debian/rules file for what they are.

on-list is better (other people benefit too). these are what i use:
for source stuff:
* apt-get source {package} - gets the *source code* of a package
* apt-get build-dep {package} - gets you the (full) build
dependencies required to *make* a source package (with
"dpkg-buildpackage)
those are typically best done in a chroot, for safety.
to find out which package has a file installed:
* grep filename /var/lib/dpkg/info/*.list
general package installing process:
* apt-cache search "keyword(s)"
* apt-cache show {package} - usually pipe this into more (or less)
* apt-get install {package} - just one.
* apt-get --purge remove {package} - just one.
these are [almost certainly] the commands that synaptics runs,
behind-the-scenes. for me, GUIs just irritate me beyond belief,
because they typically require moving hands off the keyboard and onto
the mouse. i even use fvwm2 with "mouse-over equals window-focus"
very deliberately to minimise clicks. this all because i have
recurring bouts of RSI...
hth.
