[Phylobase-devl] Compilation woes

I'm not 100% sure about this. The install errors I get in Linux are  
not very reproducible, but that's my guess. For example I got a very  
similar error to the R-Forge linux build errors the first time I tried  
to build, but then slightly different errors on subsequent attempts,  
and no errors with a fresh copy of the code.

A few more things about this:
-make clean doesn't actually seem to work properly, there isn't a  
clean action defined in the ncl makefile, maybe this is part of the  
problem.
-there is a script pkg/cleanup that gets rid of a lot of the  
accumulated files. I don't know if this could be incorporated into the  
make clean action. I missed this until now but I think this is  
something that Thibaut wrote to get phylobase to compile on linux_x64  
a long while back. The message in which he describes it was pre-R- 
Forge so I'm including a copy of the text below. Sounds like part of  
the problem is indeed files not being deleted and messing up  
subsequent builds.
-if i build the package from a clean copy of the code, the following  
files are left behind.
steve at pundit:~/code/phylobase$ svn status
?      pkg.Rcheck
?      phylobase.Rcheck
?      phylobase_0.3-1.tar.gz
?      pkg/config.log
?      pkg/config.status
?      pkg/src/phylobase.so
?      pkg/src/Makevars
?      pkg/src/RcppSrc/libRcpp.a
?      pkg/src/ncl/config.log
?      pkg/src/ncl/config.status
?      pkg/src/ncl/stamp-h1
?      pkg/src/ncl/libtool
?      pkg/src/ncl/configure.lineno
?      pkg/src/ncl/Makefile
?      pkg/src/ncl/ncl/.deps
?      pkg/src/ncl/ncl/Makefile
?      pkg/src/ncl/ncl/.libs
-if I then run the cleanup script, the following files are still left:
steve at pundit:~/code/phylobase/pkg$ svn status
?      src/ncl/config.log
?      src/ncl/config.status
?      src/ncl/stamp-h1
?      src/ncl/libtool
?      src/ncl/configure.lineno
?      src/ncl/Makefile
?      src/ncl/ncl/.deps
?      src/ncl/ncl/Makefile

Hope this helps. I definitely agree about the value of having NCL in  
phylobase, let's see if we can sort out these issues.
