You were doing the builds at nearly the same time as I committed asy to TL.

You can check my notes at
    http://tug.org/svn/texlive/trunk/Build/source/doc/README.solaris?view=markup&pathrev=40919#l119
and suggest improvements.

I was fighting with different compilers without too much success. I
could perhaps fix one problem, but then it failed somewhere else. I
read that the native compiler by Solaris now supports C++11, but I
gave up at some point. The code is not really C++11, but I failed to
get the system compiler working on version 10 (and version 11 couldn't
be used to build portable binaries anyway).

I did the last step with static linking against libstdc++ manually,
but I'll try your proposal because copy-pasting the build command
manually is more likely to lead to human error.

This was my observation as well. John Bowman pointed out that
asymptote is way more limited without support for OpenGL (and
suggested not to do it), but I have no idea how to get a binary that
would work everywhere without dependency on OpenCSW. And if users
already have OpenCSW installed ... they might just as well install
asymptote from OpenCSW. We only need to try to get the package updated
there.

Check out my notes on the link above. In particular you might need this one:
    https://github.com/vectorgraphics/asymptote/issues/19
I could try to prepare a pull request, but I need to investigate which
other flags are needed.
