I always compiled Bitcoin from git, but now I get the following error (I'm using libtool 2.4.2):

CXXLD test/test_bitcoin
CXX qt/qt_bitcoin_qt-bitcoin.o
OBJCXXLD qt/bitcoin-qt
libtool: link: unable to infer tagged configuration
libtool: link: specify a tag with `--tag'
Makefile:2305: recipe for target 'qt/bitcoin-qt' failed
make[1]: *** [qt/bitcoin-qt] Error 1
make[1]: Leaving directory '/usr/local/src/git/bitcoin/src'
Makefile:551: recipe for target 'all-recursive' failed
make: *** [all-recursive] Error 1

Any hints? Thanks.
