Build fails on OS X 10.9

[Juan Rafael García Blanco <juanrgar gmail com>]

Hi,

I don’t know if this is the correct place to inform about this; maybe it’s better to file a bug report. Sorry 
anyways. I was trying to get nemiver into macports and I discovered several points of failure. I’m not sure 
if some of them can be easily fixed, i.e. some tweaks are not needed anymore even in recent linux distros. 
Please find below the list of issues that I’ve discovered so far:

- Headers belonging to tr1 are used in various places. Their inclusion is guarded by ifdefs though. The 
problem is clang++ seems to enter those sections and tries to include tr1/* headers. Starting with 10.9 OS X 
uses by default libc++ instead of libstdc++ and this new library seems to not include tr1 headers.
- Inclusion of pty.h is not properly guarded. pty.h is not included in OS X, and util.h should be used 
instead.
- ld option ‘--as-needed’ is not recognised. I couldn’t even find a description of this flag :) Is this 
really needed?

I’m going to try to fix these as best as I can. This could be a public checklist and a remainder of the work 
that needs to be done. I’ll much appreciate any comments on these; I mean, I’m assuming these issues can all 
be fixed, I can be wrong though.

Thank you very much in advance.

Best regards,
Juan.
