problems installing mrproject

[Magueta]

Hello everyone.

I'm running RedHat 8 which came with Gnome 2 and OpenOffice 1.0.1, which came with mrproject 0.6. I'm trying to upgrade to version .8 and I'm having problems. When I ./configure the first package I get the following error messages.

checking for
glib-2.0 >= 2.0.4
libxml-2.0 >= 2.4.7
gobject-2.0 gmodule-2.0
libgsf-1 >= 1.3.0
... Package libgsf-1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libgsf-1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libgsf-1' found

configure: error: Library requirements (
glib-2.0 >= 2.0.4
libxml-2.0 >= 2.4.7
gobject-2.0 gmodule-2.0
libgsf-1 >= 1.3.0
) not met; consider adjusting the PKG_CONFIG_PATH environment variable if your libraries are in a nonstandard prefix so pkg-config can find them.
.

I've tried installing the libgsf package and I've done it successfully, it's found in /usr/local/lib/pkgconfig/libgsf-1.pc. The message above asks for the directory to be added to the path and I'm unsure where that is. I've looked in the configure and configure.in files and am unable to find any explicit variable referencing the PKG_CONFIG_PATH. I've tried PKG_CONFIG_PATH=/usr/local/lib/pkgconfig/. It was such that if I echoed it the path was returned. Never mind, while writing this I exported the variable and it was available. I'm posting anyway in case anyone has a similar problem.
Thanks for reading this far. :D
