I make the lib and compile gnupg but the gpg-agent don't start and the tests
failed.

There isn't an NFS file System on the Server.
It's possible that the lib's have issues but I compile the requsite lib's new
and I receive no Errors when I run the Tests.
I think the LIBPATH is OK, e.g. ./g10/gpg can find all lib's:

ldd ./g10/gpg
./g10/gpg needs:

/usr/lib/libc.a(shr.o)
/usr/lib/libpthread.a(shr_xpg5.o)
/usr/local/lib/libgpg-error.a(libgpg-error.so.0)
/usr/lib/libintl.a(libintl.so.1)
/usr/local/lib/libgcrypt.a(libgcrypt.so.20)
/usr/local/lib/libassuan.a(libassuan.so.0)
