[gentoo-dev] [compile problem]

[Linux Java]

Hello list,
I used gcc4.0.1 before
and now downgrade to 3.4.5
now I when I compile a program it end with:

libtool: link: cannot find the library `/usr/lib/gcc/i686-pc-linux-gnu/4.0.1/libstdc++.la'

and the copilation is over.
How can I solve this problem?

thank you in advance!
