[R] libraries in $HOME/lib

I have installed zlib and png libraries in $HOME/lib with headers in
$HOME/include and would like to pass this information along when I
configure R, but cannot find the proper incantation (R-1.4.1, Solaris,
csh). From the R-admin guide, I believe that

(setenv LIBS -L$HOME/lib ; setenv CPPFLAGS -L$HOME/include ; ./configure
)

should work, but I still get

checking for png.h... no

(starting clean, no config.cache). I have tried some variations,
including

(setenv LIBS $HOME/lib ; setenv CPPFLAGS $HOME/include ; ./configure )

which breaks gcc, as things do need to be found in other places too.
Enlightment would be appreciated. (And might I suggest an example of
this in the R-admin guide, as it it may be a common problem encountered
by compiler neophytes like me.)

I think you want to use option "-I" not "-L" with CPPFLAGS
here:> setenv CPPFLAGS -I$HOME/include ;additionally you need to tell the linker where to find the
libs:> setenv LDFLAGS -L$HOME/lib -R$HOME/lib ; (at least I did...)
