#8 Problem configuring FlowDesigner 0.9.1

[Pierre]

[...]
checking for pkg-config... /usr/local/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for PACKAGE... configure: error: Package requirements (QtCore QtGui libxml-2.0) were not met:

No package 'QtCore' found
No package 'QtGui' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables PACKAGE_CFLAGS
and PACKAGE_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

configure: error: ./configure failed for qtflow

But I have qt 4.2.2 installed
