[Gambas-user] config -C is not finding some files installed on my system

[Doug Hutcheson]

I am trying to compile Gambas downloaded from Git the other day and
config is failing to find files that exist on my system, causing a
number of modules to be disabled.
For example, the output of config includes these lines:--------------
---------------------------------------------------------------------
-------checking for gb.gsl component with pkg-config... noconfigure:
WARNING: Unable to met pkg-config requirement: gslchecking for gb.gsl
headers... ./configure: line 18086: gsl-config: command not
foundnoconfigure: WARNING: Unable to find file:
gsl/gsl_cblas.hconfigure: WARNING: Unable to find file:

gsl-config: command not foundnoconfigure: WARNING: Unable to find file:
libgslcblas.soconfigure: WARNING: Unable to find file:
libgsl.soconfigure: WARNING: gb.gsl is disabled----------------------
--------------------------------------------------------------------

Yet all the files mentioned do exist;
---------------------------------------------------------------------
---------------------
$ locate gb.gsl
/usr/lib64/gambas3/gb.gsl.component
/usr/lib64/gambas3/gb.gsl.la
/usr/lib64/gambas3/gb.gsl.so
/usr/lib64/gambas3/gb.gsl.so.0
/usr/lib64/gambas3/gb.gsl.so.0.0.0
/usr/share/gambas3/info/gb.gsl.info
/usr/share/gambas3/info/gb.gsl.list

$ locate gsl-config
/usr/bin/gsl-config
---------------------------------------------------------------------
---------------------
And so on.

What have I done wrong?   "8-(

Kind regards,
