[R] Package installation problem

[John]

I'm not certain just what this problem is.  Trying to install the
"curl" package, which "tseries" wants results in the following error:

****
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libcurl', required by 'virtual:world', not found

Using PKG_CFLAGS=
Using PKG_LIBS=-lcurl
------------------------- ANTICONF ERROR ---------------------------
Configuration failed because libcurl was not found. Try installing:
 * deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
 * rpm: libcurl-devel (Fedora, CentOS, RHEL)
 * csw: libcurl_dev (Solaris)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

However, libcurl is installed, installed.  What does seem to missing is
"libcurl.pc".  The ../pkgconfig directory contains a number of
different *.pc files, but not that one.  I'm asking here first because
someone else may have already encountered and solved this.  I'm running
Fedora 32 with kde on a 4 X AMD system.  I just updated Fedora.
