on one ubuntu64 box (ubuntu 12.04) (call it A), compiling from source (from dmd.2.064.2.zip and following http://dlang.org/dmd-linux.html), I get:

$cd src/dmd

$make -f posix.mak -j8

fatal: Not a git repository (or any of the parent directories): .git

#but compiles ok

$cd ../druntime

$make -f posix.mak -j8 DMD=../dmd/dmd

#ok...

$cd ../phobos

$make -f posix.mak -j8 DMD=../dmd/dmd

awk: cannot open ../dmd/VERSION (No such file or directory) #repeated several times

The 'crc32' module has been scheduled for deprecation. Please use 'std.digest.crc' instead.

std.md5 is scheduled for deprecation. Please use std.digest.md instead

and indeed, VERSION is in ../VERSION, not ../dmd/VERSION

on another ubuntu64 box (call it B), I cannot even compile from source unless I pass DEBUG=1 flag;

without DEBUG=1 I get (after cleaning up everything):

$cd src/dmd

$make -f posix.mak -j8

#ok till this point

$cd ../druntime

$make -f posix.mak -j8 DMD=../dmd/dmd

../dmd/dmd -lib -oflib/libdruntime-linuxdefault.a -Xfdruntime.json ...#etc

*** buffer overflow detected ***: ../dmd/dmd terminated

======= Backtrace: =========

/lib/x86_64-linux-gnu/libc.so.6

#also shows those symbols:

__fortify_fail

_IO_default_xsputn

_IO_vfprintf

__vsprintf_chk

__sprintf_chk

../dmd/dmd

__libc_start_main

../dmd/dmd

======= Memory map: ========

I get the same from git master.

with DEBUG=1 it works (but with same quirks as above)
