Hello,

Thanks for your answers (that goes to everyone who answered)!

That is what I did in the first place. To make sure it didn't just take 
a long time to build, I let it run all night.
When I came back to my machine the next morning, mono had been consuming 
some 11 hours of CPU-time, with no further output on the terminal...

While I am not really a programmer (I do know a little C... but not 
*that* much), I think I do agree...
I tried to compile a simple Hello-World that used the Console only - 
half of the time, mcs would spit out an error message, half of the time 
it would hang, again eating up an entire CPU (sometimes I *am* glad to 
own an SMP-machine, hehe).
To me it looks like mcs and mono enter infinite loops from time to 
time...  But this is not really reproducible, sometimes it hangs and 
sometimes it does not, for no apparent reason.

To make sure I wasn't wasting my - and your - time, I looked into the 
issue with libm.so.[23].
After upgrading to 5.3-BETA7 and switching to X.org, I found that most 
of my X-apps did not work any more, so I had to rebuild nearly all of my 
ports. Well, and the base system, of course (having upgraded from sources).
I decided to create /etc/libmap.conf and enter
libm.so.2       libm.so.3
like /usr/ports/UPDATING suggested.
Afterwards, I rebuilt mono - it took me three tries before I had it 
installed without mono_lt hanging.

Then I retried to build Hello-World:
########################################

^C

########################################

The first build - the one I aborted - had resulted in mono hanging.

To be honest, I'm short of giving up - I am not really a fan of .Net, I 
was just going to learn it for a friend's sake who is just discovering .Net.
Personally, I am more into Perl and Python. From what I've seen so far, 
I think C# is too much like Java - static typing, Arrays of fixed size...
I mean, I am not saying C# or .Net sucks - I just don't like it so far. 
OTOH, I was strongly prejudiced against both Perl and Python before I 
actually toyed around with them a little, and then I came to like both 
*very much*. So, who knows...
And finally, I just don't trust Microsoft not to come back in a few 
years and rip everybody's head off for patent-issues or something like 
that. (I mean, if Microsoft says 'platform-independent', it means 'runs 
on several versions of windows')

Anyway, I'd like to be able to at least get this to work, so I'll try 
the tarballs from the project site.
BTW, has anyone managed to get DotGnu or Rotor to work? I haven't found 
them in the ports tree (I looked under ports/devel and ports/lang).

Thank you very much,
Benjamin
