I had an equal problem. The --with-gpg-error-prefix seems not to work as 
expected. I used following method after looking in the configure file 
(assuming libgpg-error is a subdirectory in current dir):

export GPG_ERROR_CONFIG=`pwd`/libgpg-error/src/gpg-error-config
export CPPFLAGS=-I`pwd`
export LDFLAGS=-L`pwd`
ln -sf libgpg-error/src/.libs/libgpg-error.a .
ln -sf libgpg-error/src/gpg-error.h .

In current dir (`pwd`) now are the links to the .a file and the .h file of 
gpg-error, thats why the include paths point to this.

./configure --with-gpg-error-prefix=dummy ...

...

export -n GPG_ERROR_CONFIG
export -n CPPFLAGS
export -n LDFLAGS

I hope I stripped the relevant parts from my script, so you can follow 
the idea.

Ciao
