Here's the deal. I am trying to install DCTC, direct connect text client, but when I configure I get this error message:
checking for libgcrypt-config... yes
checking gcrypt version... 1.2.2
checking for pkg-config... /usr/local/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
checking for GLIB... configure: error: Package requirements (glib-2.0 gthread-2.0) were not met:

Package glib-2.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `glib-2.0.pc'
to the PKG_CONFIG_PATH environment variable
No package 'glib-2.0' 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 GLIB_CFLAGS
and GLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

glib, and glib-devel are both installed but I keep on getting that error message. Also , when saying glib-2.0 does that mean version 2.0 , or any 2.*...

Any help is much appreciated.
