Compile Error

[Thomas Finley <tfinley8 comcast net>]

Here is the error I'm getting:

make[4]: Entering directory `/usr/src/rpm-4.0.4/popt'

I'm configuring using :
 LIBS='-L/usr/lib' CPPFLAGS='-I/usr/include' ./configure --prefix=/usr 
--disable-nls --with-python

I have popt 1.6.4 installed.

Any help would be appreciated.
