[R] Trouble compiling igraph. . .

[jim smith]

Been and R-user for about 5 years now in an industrial setting, and
always find the mailing list most helpful.  I have run into problem
compiling igraph on R.  I have contacted the maintainer of igraph, and
he has determined that it is not an igraph problem.

System is FreeBSD 7.2, R-2.10.1 [also have a sandbox machine running
FreeBSD 7.3, R-2.11].  Both machines fail the installation of igraph.
Here is the error:

Error in dyn.load(file, DLLpath = DLLpath, ...) : 
  unable to load shared library
'/usr/local/lib/R/library/igraph/libs/igraph.so': /usr/lib/libstdc+
+.so.6: version GLIBCXX_3.4.11 required
by /usr/local/lib/R/library/igraph/libs/igraph.so not found
Error : .onLoad failed in 'loadNamespace' for 'igraph'

I built the package, then ran the linker ldd to determine if libstdc+
+.so.6 were in the correct place [and found by igraph]:


libxml2.so.5 => /usr/local/lib/libxml2.so.5 (0x340e0000)
libz.so.4 => /lib/libz.so.4 (0x33d89000)

libncurses.so.7 => /lib/libncurses.so.7 (0x34a27000)
libthr.so.3 => /lib/libthr.so.3 (0x34a66000)
libicudata.so.38 => /usr/local/lib/libicudata.so.38 (0x34a7b000)

So it appears to be there, but still I get this error.  Any guidance?
Thanks.
