LinuxQuestions.org - [SOLVED] Another compilation error (plasma-runtime). -rpath -rpath-link

Problem's with plasma-runtime-4.8.3 compilation. At very end of compilation (99%) there comes an error sayin':

Code:

/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../x86_64-pc-linux-gnu/bin/ld: warning: libqca.so.2, needed by /usr/lib64/libplasma.so.3.0.0, not found (try using -rpath or -rpath-link)

/usr/lib64/libplasma.so.3.0.0: undefined reference to `QCA::PrivateKey::signature()'

/usr/lib64/libplasma.so.3.0.0: undefined reference to `QCA::KeyGenerator::createRSA(int, int, QString const&)'

/usr/lib64/libplasma.so.3.0.0: undefined reference to `QCA::Hash::final()'

/usr/lib64/libplasma.so.3.0.0: undefined reference to `QCA::PublicKey::fromPEM(QString const&, QCA::ConvertResult*, QString const&)'

/usr/lib64/libplasma.so.3.0.0: undefined reference to `QCA::PKey::isNull() const'

(...)

I tried to compile it with:
LDFLAGS="-rpath" also tried with -rpath-link and -L=/usr/lib64/qca2/. None of them helped. It's a bit frustrating cuz I had no problems like that with any of previous gentoo installations and with any updates of kde too.
