AFAICT, it's got nothing to do with galeon or libtool. the error is
happening during the ./configure stage of compiling when it's testing to
find out if i have a working C++ compiler.

at first cc1plus wasn't in the path then when i "fixed" that, crtbegin.o
couldn't be found. for some reason, the c++ compiler is not looking in
the right directory/directories for the files it needs.

i don't know yet whether that means there is something wrong with the
packages or with my system.

i have no idea how long it has been like this as i don't usually have
any need/use for a C++ compiler...i only discovered it because i wanted
to compile the latest galeon against the latest mozilla-dev.

i don't have libstdc++3-dev installed.  i have:

ii  libstdc++2.10  2.95.2-14      The GNU stdc++ library
ii  libstdc++2.10- 2.95.4-0.01050 The GNU stdc++ library (development files)
ii  libstdc++2.10- 2.95.4-0.01050 The GNU stdc++ library
ii  libstdc++2.8   2.90.29-2      The GNU stdc++ library (old egcs version)
ii  libstdc++2.9-g 2.91.66-4      The GNU stdc++ library (old egcs version)
ii  libstdc++3     3.0-0pre010427 The GNU stdc++ library version 3

the only libstdc++  -dev package installed is libstdc++2.10-dev

just on the off-chance that i was completely mistaken about what's going
on here, i tried this - i moved them out of /usr/lib and tried compiling
again. it made no difference at all:


configure:1411: checking whether the C++ compiler (c++  ) works
configure:1427: c++ -o conftest    conftest.C  1>&5
cpp: -lang-c++: linker input file unused since linking not done
ld: cannot open crtbegin.o: No such file or directory
configure: failed program was:

#line 1422 "configure"
#include "confdefs.h"

int main(){return(0);}



FYI, there are two instances of crtbegin.o on my system:

# dlocate crtbegin.o
gcc-3.0: /usr/lib/gcc-lib/i386-linux/3.0/crtbegin.o
gcc-2.95: /usr/lib/gcc-lib/i386-linux/2.95.4/crtbegin.o

# ls -l /usr/lib/gcc-lib/i386-linux/3.0/crtbegin.o /usr/lib/gcc-lib/i386-linux/2.95.4/crtbegin.o
-rw-r--r--    1 root     root         1912 May  6 23:45 /usr/lib/gcc-lib/i386-linux/2.95.4/crtbegin.o
-rw-r--r--    1 root     root         1864 May  1 22:15 /usr/lib/gcc-lib/i386-linux/3.0/crtbegin.o
