Trying to install - libc.so.6(GLIBC_PRIVATE)

[mycoy]

Hi, all:
I'm trying install a "libc6-dev". I first downloaded a "libc6-dev_2.3.6.ds1-13etch9+b1_i386.deb" and then make a rpm package from it.
When I try to install the libc6-dev-2.3.6.ds1-14.i386.rpm, I get

error: Failed dependencies:
        libc.so.6(GLIBC_PRIVATE) is needed by libc6-dev-2.3.6.ds1-14.i386

I find that I have installed "glibc-2.9-3.i686" and "libc.so.6" should be in it.
I'm not sure what does "GLIBC_PRIVATE" mean, and how to solve the problem?
I'm using Fedora10-i686, gcc4.

Could anyone help me? Thanks
